K. P. invoked the provisions of ORS 137.225 to seal the records of her misdemeanor conviction (for theft in the second degree, a Class A misdemeanor under ORS 164.045) by filing a motion entitled “Motion To Set Aside Records Of Arrest And Conviction.” As is statutorily required for eligibility to make the motion, more than three years had elapsed after entry of the misdemeanor judgment against her. K. P. had successfully served the probationary sentence imposed and had not been in any further criminal difficulty.
ORS 137.225 provides in part:
“(l)(a) At any time after the lapse of three years from the date of pronouncement of judgment, any defendant who has fully complied with and performed the sentence of the court and whose conviction is described in subsection (5) of this section by motion may apply to the court wherein that conviction was entered for entry of an order setting aside the conviction; * * *
‡ ‡ *
“(3) * * * Upon the entry of such an order, the applicant for purposes of the law shall be deemed not to have been previously convicted, or arrested as the case may be, and the court shall issue an order sealing the record of conviction and other official records in the case, including the records of arrest whether or not the arrest resulted in a further criminal proceeding.
‡ ‡ ‡
“(10) Upon motion of any prosecutor or defendant in a case involving records sealed under this section, supported by affidavit showing good cause, the court with jurisdiction may order the reopening and disclosure of any records sealed under this section for the limited purpose of assisting the investigation of the movant [prosecutor]. However, such an order shall have no other effect on the orders setting aside the conviction or the arrest record.” (Emphasis added.)
As can be seen, the statute requires that the conviction or record of arrest be “set aside” and that other official records be “sealed.”
*4Because K. P. qualified for the relief that the statute provides, the trial court judge allowed the motion and requested that K P.’s counsel prepare an order detailing the relief granted. K. P.’s counsel presented a proposed order to the court that provides in part:
“The records of arrest and conviction, and all other official records in this case, including police investigation reports, shall be sealed.” (Emphasis added.)
Before signing that order, the court deleted the word “including” and substituted in its place the word “excluding.” Thus, as entered, the order excluded “police investigation reports” from being sealed.
On review, K. P. contends that the district court judge erred by excluding the police investigative reports concerning the underlying misdemeanor from the records to be sealed. K. P. relies on the words of the statute that require that the judge who enters the order “shall” issue an order sealing “other official records in the case.” K. P. argues that the statute requires that police investigative reports related to the original crime of conviction must be sealed, because they are included within the scope of that statutory phrase. The substantive issue presented by this case is whether the legislature intended that police investigative reports related to the criminal case be included in the statutory phrase “other official records in the case.” If those reports are included, ORS 137.225 requires that they be sealed.
However, a threshold procedural issue arises. That issue is whether the order setting aside the conviction and sealing records is appealable. To exist, the right of appeal must be conferred by a statute. State v. Curran, 291 Or 119, 122, 628 P2d 1198 (1981). Without such a statute, there is no jurisdiction to consider an attempted appeal. McEwen et ux v. McEwen et al, 203 Or 460, 470, 280 P2d 402 (1955). Unless jurisdiction on appeal is present, the court may not reach any substantive issues presented. Ibid. Thus, we start by reviewing the statutes that authorize various kinds of appeal. When one starts to analyze those statutes, another important question immediately arises: Is appeal in a proceeding to seal a record pursuant to ORS 137.225 covered by ORS chapter 138, *5relating to appeals in criminal cases or, instead, by some provision in ORS chapter 19, relating to appeals generally? We sought guidance on that question by asking counsel for the state and for K. P. to answer this question:
“What statute authorized an appeal of the trial court’s order to the Court of Appeals?”
Both parties answered that a subsection of ORS 19.010 confers appellate jurisdiction1 in this case, but they pointed to different subsections of that statute. K. P. states that ORS 19.010(2)(c) creates a right of appeal in this case. The state agrees that appellate jurisdiction is conferred by ORS 19.010, but points to subsection (4).
Because this case is about the record in a previous criminal case, we first consider whether a motion to set aside a conviction under ORS 137.225 may be considered a request for relief in other than a criminal case, i.e., in a civil matter as to which ORS chapter 19 governs.2 To answer that question, we examine the function served by a proceeding to set aside a conviction and to seal related records.
Although sealing the records of an old misdemeanor may further a policy of rehabilitation or reformation for criminals, the proceeding to accomplish it is not in the nature of an action to punish a criminal violation, i.e., it is not (in that sense) a criminal proceeding. As ORS 137.255(3) mandates, thereafter the person “shall be deemed not to have been previously convicted” or arrested, as the case may be.
Based on the rehabilitative function performed by the statutory proceeding, we hold that a motion to set aside the conviction or arrest and to seal records is not a criminal action. Thus, an appeal of the ruling on that motion made under ORS 137.225 is not governed by ORS chapter 138. We *6therefore turn our attention to ORS chapter 19, governing civil appeals.
K. P.’s suggestion that this statutory proceeding is ancillary to the criminal judgment and, therefore, that ORS 19.010(2)(c) governs, is wide of the mark. This proceeding is unlike a writ of assistance or an execution by which a prior judgment is carried out with additional court assistance. Neither is this proceeding like a reinstatement of a sentence or imposition of one previously suspended. Indeed, an ORS 137.225 proceeding is the antithesis of the original criminal conviction, not an adjunct to it. For those reasons, we do not believe that ORS 19.010(2)(c) applies to make an order made pursuant to ORS 137.225 appealable.
On the other hand, we believe that the state’s argument — that ORS 137.225 is a “special statutory proceeding” appealable under ORS 19.010(4) — is apt. Accordingly, we hold that a final order entered in a proceeding under ORS 137.225 is entered in a special statutory proceeding and that appeal of such an order is authorized by ORS 19.010(4).
We turn to the substantive issue in the case. That issue may be stated: Are police investigative reports included within the statutory phrase, “other official records in the case”?
ORS 137.225 requires that, on granting the motion to set aside records of arrest and conviction, the court shall order sealed those records and “other official records in the case.” Thus, other records of an “official” character that are related to the conviction, or an arrest that did not result in a conviction, are to be sealed.
The trial court apparently relied on State v. Smith, 117 Or App 320, 843 P2d 1015 (1992), rev den 315 Or 644 (1993), when it chose to exclude official police investigative reports in the case from being sealed. Affirming the trial court, the Court of Appeals expressly relied on Smith without further reasoning when it affirmed that exclusion from the order sealing records. State v. K. P., 133 Or App 256, 889 P2d 1370 (1995).
In Smith, decided in 1992, the Court of Appeals held in a split decision that police investigative reports were not *7“other official records in the case.” The Smith court first noted that there was no definition of “official records” in ORS 137.225. The absence of a definition was thought in Smith to equal an absence of legislative intent without further examination of the legislation.3 The majority in Smith declared:
“ P3]ad the legislature considered the issue, it would have limited the definition of‘official records’ in ORS 137.225 to exclude investigation reports.” 117 Or App at 325.
We have been provided no basis for agreeing with that exegesis. It is quite a stretch of logic to determine, from its absence, in what way a nonexistent definition would have “limited” the scope of the statute.
K. P. points out other difficulties with the Smith decision. She argues that the Smith approach is significantly different than the approach that this court takes to discern legislative intent and that the Smith result undermines the remedial and rehabilitative purposes of ORS 137.225, so that the statute’s record-cleansing function is largely undone.
K. P. argues that the intent or purpose of the legislature was to allow a person to avoid the lifelong social stigmatization and impairment of employment opportunities that otherwise would result from a single criminal conviction, or an arrest that did not result in conviction, and that sealing police reports in the case would be wholly consistent with that intent and purpose of the legislature and that failing to seal them would fly in the face of that purpose.4
In analyzing a statute, this court starts with the text and context, PGE v. Bureau of Labor and Industries, 317 Or 606, 610-11, 859 P2d 1143 (1993), and determines legislative *8intent by what is contained within the statute, not by inserting what has been omitted nor by omitting what has been inserted. ORS 174.010; State v. Trenary, 316 Or 172, 175, 850 P2d 356 (1993). Most words used by the legislature are not defined in the statute that employs them. Under PGE, 317 Or at 611, we rely on the plain, natural, and ordinary meaning of the words that the legislature chose to use.
The words in the phrase have ordinary meanings that are relatively easy to determine. “Other” means other than those enumerated. “Official” means created by a public, governmental body. “Records” means a report of something that occurred that is memorialized or kept track of, whether by print or electronic means. “In the case” means that the occurrences or events referred to and recorded are, in legal contemplation, related to the same aggregate set of operative facts as those that gave rise to the arrest record or conviction that is to be set aside, and which are also to be sealed. Whether the investigative reports in question are “in the case” is an issue of fact in each case. However, in the present case, the trial court excluded all such investigative reports related to the arrest and conviction without making any distinction or findings.
We may not omit a part of the wording of the statute in our interpretation of it. ORS 174.010. Instead, we are to give effect to all that wording. Id. That wording requires that “other official records in the case” be sealed, not just records of conviction and records of arrest. Given that understanding of text, we also look at context before declaring legislative intent. PGE, 317 Or at 611.
K. P. argues, based on the context of subsection (3), that subsection (10), added in 1983, refers to a later or second “investigation” and assumes that records ordered to be sealed could be relevant to such an investigation. She points out that subsection (10) is part of the context of subsection (3) of the statute and that subsection (10) would be meaningless unless the records that are to be sealed, under the statute, include investigative reports prepared by the police as well as reports of actual arrests. She argues, in effect, that there is little point in having a provision for unsealing records that *9will assist in a later investigation if those records are not required to be sealed in the first place.
Subsection (10) in part provides:
“Upon motion of any prosecutor or defendant in a case involving records sealed under this section, * * * the court * * * may order the reopening and disclosure of any records sealed under this section for the limited purpose of assisting the investigation of the movant.”
Nothing in that subsection suggests a basis for any inference that records of an investigation were not intended to be sealed under ORS 137.225. Subsection (10) certainly is consistent with giving a literal interpretation to “other official records in the case.”
K. P. also makes a contextual argument based on the sequence and content of amendments to ORS 137.225(3). Prior amendments of a statute are part of its context. Krieger v. Just, 319 Or 328, 336, 876 P2d 754 (1994). As originally enacted in 1971, the statute required both the setting aside and sealing of records of conviction. State v. Langan, 301 Or 1, 10, 718 P2d 719 (1986). “Other official records in the case” also were required to be sealed, and those other records included arrest records. Or Laws 1971, ch 434, § 2.
Subsection (3) was amended by Oregon Laws 1983, chapter 556, to include setting aside and sealing of records of arrest. The 1983 legislature expanded the statutes to require specifically the sealing of arrest records, even in cases where there was either no charge or no conviction following the arrest to be “set[ ] aside.” Subsection (1) was amended by adding a new paragraph (b).5 Chapter 556 also added the new subsection (10) referred to above.
*10The 1983 legislature retained the words “other official records in the case.” Retention of that phrase, while adding the new subsection provisions about sealing records of arrest in cases not resulting in a conviction, indicates that the 1983 legislature intended for that retained language to include records that are other than the record of arrest in the case of conviction, or a record of arrest in a case where either no formal charge was filed or no conviction was obtained. The amendment history of the statute supports K. P.’s reading of the wording as including other official records as well as arrest records.
In its brief to the Court of Appeals, the state argued that the public records law, ORS chapter 192, is part of the context of ORS 137.225 and, because the public records law defines criminal law investigative reports as confidential records exempt from public disclosure, such reports cannot be “official” records. The state relies on ORS 192.501(3), which exempts from disclosure, unless the public interest requires it:
“Investigatory information compiled for criminal law purposes.”
That argument is not persuasive. We reject that argument, because an exemption from disclosure in the public records law found in ORS 192.501 simply says nothing about whether the legislature intended to prevent sealing an official record under ORS 137.225.
Moreover, ORS 192.501(3) confirms that police investigatory reports are official records. Were that not so, there would be no occasion to deal with such records as “public” records to be exempted from disclosure. ORS 192.501(3) provides a complementary exemption from disclosure of such investigatory information compiled for criminal law purposes in circumstances in which an order setting aside and sealing the record of arrest or conviction is not present.
The state makes other arguments that, if they were well taken, would in effect remove the words “other official records in the case” from the operative effects of ORS *11137.225(3). Although innovative, those arguments are not well taken.6
The word “other” signifies something in addition to a record of conviction or a record of arrest. The trailing specific phrase “including the records of arrest” indicates that the “other official records” referred to are not records of arrest, although they may be similar to them. That phrase further designates one example of what are other official records and denotes that a conviction record is not necessary to make the provision for sealing other “official records” applicable.7
As stated above, we take the words “official records” to mean records created by a government agency. The police are an agency of government; police reports are “official records.” However, as noted, the only official records mandated to be sealed are those “in the case” as to which a motion under ORS 137.225 has been filed and granted. A case-by-case, fact-specific inquiry must be undertaken where the issue arises that the records addressed are not records in the case, but no such issue is raised in this “case.”
*12The district court erred when it created an exception not found in ORS 137.225. The portion of the district court’s order that affirmatively excluded from sealing certain official records in the case, i.e., police investigative reports in the case, constituted error depriving K. P. of the relief to which the statute entitles her.
The decision of the Court of Appeals is reversed. That part of the district court order excluding certain records in the case from the remaining provisions of the order is vacated, and this case is remanded to the district court for further proceedings.
