Defendant, Casimir Grabowski, was tried by jury and convicted of violating the bank, safe and vault robbery statute, CL 1948, § 750.531 (Stat Ann 1954 Eev § 28.799) and breaking and entering a business place contrary to MCLA § 750-.110 (Stat Ann 1969 Cum Supp § 28.305). On appeal it is contended that the safecracking statute is unconstitutionally vague and ambiguous. The people have filed a motion to affirm the conviction.

*13The defendant’s suggested interpretation of the bank, safe and vault robbery act is unreasonable. The questions presented here on appeal are unsubstantial and require no formal argument or submission.

Affirmed.
