¶1OPINION
¶2A joint trial of two separate aggravated robbery indictments arising from the same criminal episode resulted in the conviction of appellant in both cases. The jury assessed punishment at thirty years confinement in each case. Appellant complains that the trial court improperly instructed the jury during the punishment phase that the sentences on both charges would run concurrently. V.T.C.A. Penal Code, Sec. 3.03. We affirm.
¶3Following his convictions in the “guilt-innocence” phase of the trial, appellant elected to go the jury for punishment. While deliberating punishment, the jury sent a written request to the court:
*728“Will the two sentences run concurrently?”
¶4The court responded in writing as follows:
“In answer to your note which has been identified as C-2, when an accused is found guilty of more than one offense arising out of the same criminal episode prosecuted in a single criminal action, as was done in this instance, sentence for each offense for which he has been found guilty shall run concurrently. The answer to your question is ‘yes.’ ”
¶5Appellant objected to the submission of this additional charge to the jury. Appellant raises two grounds of error, both directed toward the supplemental instruction to the jury. Appellant argues that the supplemental charge contained information not proper for jury consideration and, therefore, consideration of concurrent sentencing in the punishment phase denied appellant of the benefit of V.T.C.A. Penal Code, Sec. 3.03. Appellant claims this harm resulted in an unfair trial with the jury returning a more severe penalty than they would have done without the instruction.
¶6Both appellant and the State concede that the issue here presented is one of first impression.
¶7Initially, we are concerned with appellant’s claim of harm arising from the supplemental instruction. Our examination of the record does not reflect any harm to appellant that might be traced to the additional charge. The record before us shows only that the jury was concerned with concurrent sentencing and requested information from the court. There is no showing that the jury’s consideration of the information supplied by the court worked to the detriment of appellant.
¶8Further, we are unable to presume harm in this situation. Knowledge that the sentences would run concurrently is a two-edged sword. The information could have been used to increase the punishment or, just as easily, used to reduce the number of years to avoid excessive punishment. We cannot determine from the record which path the jury took and, with these alternatives, harm will not be presumed.
¶9We now consider the propriety of jury consideration of concurrent sentencing in a fact situation where V.T.C.A. Penal Code, Sec. 3.03 is applicable with the focus being on whether such information is a proper matter for jury consideration. Appellant argues that concurrent sentencing is not a matter to be considered by a jury, comparing to situations involving parole and situations wherein punishment is absolutely fixed by law. If the consideration of concurrent sentencing is proper, then the jury, after retiring to deliberate and upon proper request, should be instructed. On the other hand, if this subject matter is not a proper consideration, then a supplemental instruction would be error. Allaben v. State, 418 S.W.2d 517 (Tex.Cr.App.1967).
¶10Appellant argues that his situation presents for our consideration the same reasoning as do the cases involving jury consideration of parole or consideration of punishment absolutely fixed by law. We find the reasoning in neither applicable to the present case.
¶11Parole is a matter within the exclusive jurisdiction of the Board of Pardons and Paroles and, as such, is not a matter of concern for a jury. Williams v. State, 511 S.W.2d 64 (Tex.Cr.App.1974). Parole then is an executive function, and the jury should not concern itself with executive decision-making.
¶12Appellant finally argues that the supplemental charge was improper because it denied him the benefit of V.T.C.A. Penal Code, Sec. 3.03. While appellant does not state the nature of the benefit he was denied, the conclusion drawn from appellant’s argument suggests that by electing joint trials an appellant is guaranteed a less severe penalty than if the causes were severed. At least, appellant suggests that Sec. 3.03 guarantees him that punishment will be assessed by a jury ignorant of the law. We do not feel that such an advantage is expressed nor may it be implied from the language of Sec. 3.03.
¶13To determine the purpose of Sec. 3.03, we turn first to the practice commentary following that section. The language of that commentary indicates that Sec. 3.03 does no more than treat “multiple convictions resulting from prosecution of joined offenses as a single conviction for sentencing purposes.” V.T.C.A. Penal Code, Sec. 3.03, practice commentary at p. 77. The purpose of the statute appears to be convenience and efficiency, permitting one trial on the joined counts, and treating the separate offenses as one for sentencing purposes.
¶14There is no guarantee in Sec. 3.03 that a joint trial of the offenses will result in a less severe penalty than separate trials of the same offense. We find the only benefit assured appellant by the language of Sec. 3.03 is concurrent sentencing. The inducement to appellant not to seek a severance of joined offenses is that his risk will be reduced (not eliminated) because the sentencing will be concurrent as opposed to consecutive.
¶15The policy of the law should require juries to make informed and intelligent decisions based on every piece of information legally available.
¶16We hold that the trial court did not abuse its discretion by giving the additional charge to the jury, as such charge contained information which was a proper matter for jury consideration.
¶17The judgment is affirmed.
¶18. In final argument, appellant requested the minimum punishment (five years) while the State asked for fifty years. The jury assessed thirty year terms.
¶19. See Alexander v. State, 482 S.W.2d 862 at 864 (Tex.Cr.App.1972) indicating that if sentences are concurrent, argument by the State that the sentences would run concurrently is harmless.
¶20. Several jurisdictions permit jury consideration of the laws surrounding length of time served or hold that such information is harmless if in the penalty stage. Feggins v. State, 359 N.E.2d 517 (S.Ct.Ind.1977); Armstrong v. State, 548 S.W.2d 334 (Tenn.Cr.App.1976); State v. Canfield, 26 Utah 2d 149, 486 P.2d 1034 (1971); Radcliff v. State, 490 P.2d 1398 (Okl.Cr.App.1971); Abernathy v. Commonwealth, 439 S.W.2d 949 (Ky.Ct.App.1969); *729State v. Shilow, 252 La. 1105, 215 So.2d 828 (1968); People v. DeBerry, 72 Ill.App.2d 279, 219 N.E.2d 701 (1966).
¶21. Jury consideration of Sec. 3.03 compares favorably with a court’s authority to consider unadjudicated offenses in the punishment phase. See V.T.C.A. Penal Code, Sec. 12.45.
¶22. Juries regularly consider probation conditions in appropriate cases. Gleffe v. State, 501 S.W.2d 672 (Tex.Cr.App.1973).
