Unable to make bail, the defendant Carter was incarcerated while awaiting trial on four indictments, two for assault with intent to murder (G. L. c. 265, § 15) and two for assault and battery by means of a dangerous weapon (G. L. c. 265, § 15A). 1 Of these charges the defendant was convicted, and his appeal raises questions as to: (1) the number of days his prison term should have been reduced by reason of his detention in jail while awaiting trial and sentencing; and (2) certain claimed errors in the instructions to the jury.
*619 1. Jail credits. The defendant received sentences of consecutive prison terms of not less than seven nor more than ten years for the two assaults with intent to murder and sentences of the same duration for the assaults and batteries with a dangerous weapon, the latter sentences to be served concurrently with the others.
When he was sentenced the defendant had already spent 398 days in jail awaiting trial and during trial. For this the trial judge gave the defendant credit against one of the sentences he was to serve consecutively. General Laws c. 279, § 33A, as appearing in St. 1961, c. 75, 2 requires a sentencing judge to give a defendant credit for time served in jail before sentencing while awaiting trial and during trial. It is the defendant’s contention that the statute entitles him to 398 days’ credit on each of the consecutive sentences, i.e., an aggregate of 796 days’ credit.
In order to reach this result the defendant makes a grammatical argument: The statute speaks of the prisoner as one deemed to have served so much of his sentence (singular), as opposed to sentences (plural), as he spent in confinement before receiving the sentence; thus, the argument proceeds, if a person receives multiple sentences, the credit must be applied to each of them. Because the statute affects liberty, the defendant contends, it is penal in nature (see
Allen
v.
Massachusetts Parole Bd.,
This essentially technical argument could fairly be answered by a countervailing technical one, that G. L. c. 4,
*620
§ 6, lays down a rule of construction that “[w]ords importing the singular number may extend and be applied to several persons or things . . . .” See

v.
Damon,
Much more to the point, however, is that the Legislature in enacting G. L. c. 279, § 33A, had in mind that it would be a “fair and worthwhile practice” to grant a prisoner credit for time in confinement before imposition of sentence. Report and Recommendations of the Governor’s Committee to Study the Massachusetts Correctional System, 1955 Senate Doc. No. 750, at 75. In keeping with that intent, the approach in the cases has been to consider the subject of jail credits “against the backdrop of fair treatment of the prisoner.”
Commonwealth
v.
Grant,
From what we have said it follows that were a sentence to expire with jail time credit unexhausted, that remaining time is to be applied to the balance of concurrent and consecutive sentences left to be served. Any sentence being served concurrently with a sentence to which a jail credit is applied should receive the benefit of the same credit so that the sentence in fact retains a concurrent status.
2.
Claimed errors in jury instructions.
Although trial counsel took three exceptions to the judge’s charge to the jury, none of those is argued on appeal. Rather the defendant raises claims of defect in the instructions not called to the attention of the judge at the time of trial. A claim of error not called to the attention of the trial court brings nothing to this court for review,
Commonwealth
v.
Stokes,
There is no merit whatever to the defendant’s complaint that the judge shifted to him the burden of disproving malice. He charged repeatedly and properly that the Commonwealth had to prove each element of the crime and that “nothing is to be presumed against the defendant.” See

Notes
Each of the crimes alleged was committed on two victims, hence the four indictments.
The full text of § 33A, is as follows: “The court on imposing a sentence of commitment to a correctional institution of the commonwealth, a house of correction, or a jail, shall order that the prisoner be deemed to have served a portion of said sentence, such portion to be the number of days spent by the prisoner in confinement prior to such sentence awaiting and during trial.”
G. L. c. 127, § 129B, as appearing in St. 1961, c. 74.
A prisoner does not generally receive credit for jail time served for an unrelated offense.
