532 P.2d 1140 (1975)
STATE of Oregon, Respondent,
v.
Stephen Duane THOMPSON, Appellant.
Court of Appeals of Oregon.
Argued and Submitted February 18, 1975.
Decided March 10, 1975.
*1141 Gary D. Babcock, Public Defender, Salem, argued the cause and filed the brief for appellant.
Thomas H. Denney, Asst. Atty. Gen., Salem, argued the cause for respondent. With him on the brief were Lee Johnson, Atty. Gen., and W. Michael Gillette, Sol. Gen., Salem.
Before SCHWAB, C.J., and LANGTRY and LEE, JJ.
SCHWAB, Chief Judge.
Defendant was charged under a three-count indictment with two counts of first degree robbery in violation of ORS 164.415[1] and one count of violating ORS 166.270[2] which prohibits a convicted felon from possessing a concealable weapon. The two robbery counts involved robbery of two separate persons at the same time and place. Upon trial by jury defendant was found guilty on all three counts.
At sentencing, the trial court treated the crimes charged in each of the three counts as merged and imposed sentence on the first robbery count only, specifically, 15 years' imprisonment. The court imposed an additional five-year sentence under ORS 166.230(1),[3] which authorizes an additional penalty for commission of a felony *1142 while in possession of an unlicensed concealable firearm.
Defendant appeals on the ground that a material element necessary for a violation of ORS 166.230(1)  the fact that defendant was not licensed to carry the firearm  was not alleged in the indictment as is required by State v. Blacker, 234 Or. 131, 380 P.2d 789 (1963), and that therefore the indictment was insufficient to charge that act and the court had no jurisdiction to impose the additional five-year sentence. The defendant asks that this sentence be vacated.
The state concedes that the indictment was not sufficient to charge a violation of ORS 166.230, and that the five-year sentence was erroneously imposed. However, the state argues that the court also erred in merging the crimes charged by the three counts of the indictment, and that therefore the correct remedy would be to remand the entire case for resentencing so that all of the errors could be corrected.
The lower court's action in merging the three crimes was erroneous. State v. Woolard, 259 Or. 232, 484 P.2d 314, 485 P.2d 1194 (1971), specifically did not apply to a course of conduct where the same statute was violated several times. See, State v. Rook, 14 Or. App. 211, 511 P.2d 1245, Sup.Ct. review denied (1973). And this court held in State v. Sortor, 10 Or. App. 316, 499 P.2d 1370 (1972), that the offenses of assault with intent to rob and being an ex-convict in possession of a firearm do not merge.
Nevertheless, we cannot correct that error in this proceeding. So far as the record discloses, no dispositive order has ever been entered on the two counts on which the trial judge did not sentence the defendant. All we find in the record is the judgment order sentencing the defendant on the first count, and the trial judge's oral statement from the bench:
"It will be the sentence of the court  I am going to treat these as a merger situation  I am going to sentence you to 15 years on the first count of robbery."
If the state assumed that the above language, coupled with the judgment order on the first robbery count, constituted an order dismissing the other two counts, it did not appeal, although a strong argument can be made that the state was authorized to do so under ORS 138.060(2).[4] If the state's position was that the trial court had a duty to enter a dispositive order as to each of the counts, and there is authority for this proposition, see, State v. Meyer, 12 Or. App. 486, 507 P.2d 824 (1973), the state's remedy was to institute a separate proceeding such as mandamus seeking to require the trial court to enter a dispositive order as to each of the counts. We note that the record does not disclose that either counsel requested a dispositive order. In any event, the only question properly before us is the validity of the additional five-year sentence imposed under ORS 166.230. This sentence the state concedes was erroneously imposed and it therefore must be vacated.
Affirmed in part; reversed in part.
