Following a jury trial, appellant was convicted of twenty-seven counts each of theft by deception, receiving stolen property, and misapplication of government property, as well as one count each of tampering with witnesses and criminal conspiracy. For the reasons that follow, we find appellant’s contentions meritless and, accordingly, affirm the judgment of sentence.
I.
Appellant contends that the lower court erred in denying his pre-trial motion to dismiss the charges on the ground that the statute of limitations had expired. All of the offenses relate to a ghost employee scheme perpetrated while appellant was the director of the Allegheny County Department of Manpower (ACDOM). They would, therefore, be subject to the two-year statute of limitations contained in 18 Pa.C.S.A. § 108(b)(2) (repealed). 1 However,
[i]f the period prescribed in [18 Pa.C.S.A. § 108(b)(2)] has expired, a prosecution may nevertheless be commenced for:
(2) Any offense committed by a public officer or employe in the course of or in connection with his office or employment at any time when the defendant is in *435 public office or employment or within two years thereafter, but in no case shall this paragraph extend the period of limitation otherwise applicable by more than three years.
18 Pa.C.S.A. § 108(c)(2) (repealed). Appellant argues that subsection 108(c)(2) of the Crimes Code requires that the prosecution of a public officer or employe be commenced within two years of his leaving the particular “public office or employment” occupied at the time he committed the offenses charged. 2 Accordingly, because the informations were not filed until April 20, 1978, two years and one day after appellant left ACDOM, his prosecution would be barred by the statute of limitations. We disagree. Appellant’s construction of subsection 108(c)(2) is unduly restrictive. The phrases “public officer or employe” and “office or employment” are not limited or qualified. By contrast, the predecessor to subsection 108(c)(2) contained an express limitation or qualification of the nature advocated by appellant.
And provided also, That indictments for malfeasance, misfeasance, or nonfeasance in office, or for extortion or blackmail by color of office, or for embezzlement of public moneys or property, or for any misdemeanor in office, or for any conspiracy to commit any of said offenses heretofore or hereafter committed by any officer or employe of this Commonwealth or of any agency thereof, or of any city, county, borough, township, or school district or of any agency thereof, and their accomplices and confederates, may be brought or exhibited at any time within two years from the time when said public officer or said employe shall have ceased to occupy such office or such employment, but in no event more than six years from the commission of the offense.
Act of March 31,1860, P.L. 427, § 77, as amended by the Act of April 6, 1939, P.L. 17, § 1; 19 P.S. § 211 (repealed) *436 (emphasis added). 3 Consequently, we construe subsection 108(c)(2) as providing an exception to the statute of limitations whenever the “public officer or employe” has continuously occupied any “office or employment,” and not just the particular “office or employment” occupied at the time of the offense. See Statutory Construction Act of 1972, Act of December 6, 1972, No. 290, § 3, 1 Pa.C.S.A. § 1921(c)(5) (in determining legislative intent, court may consider “[t]he former law, if any, . . . upon the same or similar subjects”). It is thus of no consequence that appellant left ACDOM on April 19, 1976, because he immediately was transferred to the payroll of the Allegheny County Commissioners where he remained as a commissioner’s secretary until March 22, 1977. He was, therefore, continuously a “public officer or employe” from the time of the commission of the offenses until March 22, 1977. Thus, because the informations were filed approximately thirteen months after appellant left “public office or employment,” his prosecution was timely commenced. 4 Accordingly, the lower court properly denied his pre-trial motion to dismiss the charges. 5
II.
The incidents underlying this appeal concern appellant’s involvement with Robert Ficklin. At trial, the Commonwealth introduced over appellant’s objection, evidence concerning appellant’s involvement in substantially similar *437 schemes with others not mentioned in the present informations. Appellant contends that the lower court erred in admitting this evidence of other crimes because he was unable to prepare an adequate defense.
The prosecution generally may not introduce evidence that a defendant has committed other crimes as evidence of his guilt for the particular crime charged.
See, e.g., Commonwealth v. Stanley,
Appellant concedes that the challenged evidence falls within any number of the above exceptions, is logically connected to the crimes charged, and would be admissible but for the inherent prejudice from his inability to prepare an adequate refutation of that evidence. We disagree. “When the evidence is relevant and important to one of these [exceptions], it is generally conceded that the prejudicial effect may be outweighed by the probative value.”
Commonwealth v. Peterson, supra
at 198,
[Appellant’s] present, as well as his prior counsel, have at all times had available to them the statements of all witnesses whether relating to the present information or [the] other informations, and the grand jury testimony relating to all cases. In addition, during the course of trial, which lasted some three weeks, the Commonwealth sought a preliminary ruling from the trial judge concerning the admissibility of such evidence before it was presented.... He and his counsel at all times have been fully aware of all of the charges and all of the government’s evidence against him relating to those charges. Thus, it appears that not only was the information in fact available to [appellant] prior to and during the trial, he could have received, by resort to [Pa.R.Crim.P.] 305, any additional information that he might have desired. The vigorous and thorough use by defense counsel at the trial, of statements and grand jury testimony in cross-examining witnesses and in meeting the Commonwealth’s evi *439 dence belies the claim now made by him that in some way his defense was hampered.
Consequently, we conclude that the lower court did not err in admitting the challenged evidence. 6
III.
Appellant contends also that the lower court erred in: (A) sua sponte instructing the jury not to consider the consequences to appellant if they were to return a guilty verdict; (B) refusing to specifically identify for the jury several allegedly key Commonwealth witnesses whose testimony should have been closely scrutinized because they were among appellant’s accomplices; (C) refusing to charge that lack of force was not an element of the misdemeanor offense of tampering with witnesses; and (D) improperly instructing concerning the requisite mental element of misapplication of government property. We find, however, that the trial judge adequately instructed the jury.
A.
The trial judge specifically instructed the jury that it was not to consider the consequences to appellant were they to return a guilty verdict. The instruction, based upon that given in
Commonwealth v. Corbin,
B.
Appellant argues that the trial judge should have specifically identified for the jury the names of several accomplice-witnesses. We disagree. The court is free to select its own form of expression in charging the jury, so long as the issue is adequately, accurately, and clearly presented. When the basic charge covers a requested point, it is not error to refuse to give additional instructions.
Commonwealth v. Newsome,
*441 C.
Appellant argues next that the lower court erred in refusing to charge the jury that lack of force was not an element of the misdemeanor of tampering with witnesses. We disagree. A trial judge has a duty to clarify the relevant issues “so that the jury may comprehend the questions they are to decide and not only to state to the jury correct principles of law applicable to the pending case.”
Commonwealth v. Davison,
Tampering with witnesses and informants.
(a) Offense defined.—A person commits an offense if, believing that an official proceeding or investigation is pending or about to be instituted, he attempts to induce or otherwise cause a witness or informant to:
(1) testify or inform falsely;
*442 (2) withhold any testimony, information, document or thing except on advice of counsel;
(3) elude legal process summoning him to testify or supply evidence; or
(4) absent himself from any proceeding or investigation to which he has been legally summoned.
(b) Grading.—The offense is a felony of the third degree if the actor employs force, deception, threat or offer of pecuniary benefit. Otherwise it is a misdemeanor of the second degree.
18 Pa.C.S.A. § 4907. Appellant was charged only with the misdemeanor version of the offense. Thus, use of force was an irrelevant consideration.
See Commonwealth v. Hobson,
D.
Appellant’s final challenge to the jury charge concerns the requisite mental element of misapplication of government property. In reviewing a trial court’s instructions to the jury, an appellate court must consider the entire charge and its general effect controls.
See, e.g., Commonwealth v. Woodward,
Judgment of sentence affirmed.
Notes
. This case arose before the effective date of the time limitations contained in the Judicial Code, 42 Pa.C.S.A. § 5552(a), (c).
. “An offense is committed either when every element occurs, or ... when [a continuing] course of conduct or the complicity of the defendant therein is terminated. Time starts to run on the day after the offense is committed.” 18 Pa.C.S.A. § 108(d) (repealed).
. The Act of March 31, 1860, was not expressly repealed by section 108 of the Crimes Code, 18 Pa.C.S.A. § 108, but the Judicial Code repealed both.
See Commonwealth v. Bidner,
. Because of our disposition of this issue, we need not address the lower court’s alternative bases for sustaining the timeliness of the prosecution.
. Appellant argues also that the lower court erred in failing to submit the statute of limitations issue to the jury. We disagree. When the evidence substantiating an exception to the statute of limitations is unrebutted, the trial judge may take the issue from the jury.
Commonwealth v. Hoffman,
. Appellant argues also that because the Commonwealth is not required to provide pretrial notice that it intends to introduce evidence of other crimes not charged, he was denied various constitutional protections. Because issues, even those of constitutional dimension, cannot be raised for the first time on appeal, his contentions have been waived. Pa.R.A.P. 302(a);
Wiegand v. Wiegand,
. Contrary to appellant’s assertion, the instruction did not unduly chastise defense counsel. Indeed, the trial judge’s prefatory remarks complimented both sides for their diligence at trial.
. Appellant argues also that the lower court erred in failing to give a “strong charge” concerning the credibility of accomplice-witnesses.
See Commonwealth v. Didio,
. Appellant argues also that the Commonwealth unconstitutionally deprived him of a prospective defense witness by advising the court and defense counsel that it was then in the process of preparing a perjury information against the witness. This issue has been waived because appellant failed to assert it in his post-trial motions. Pa.R. A.P. 302(a);
