Summary :

This paper presents consize proof rules for procedure calls in Pascal-like programs. Procedures which we deal with may contain recursive calls and have both variable parameters and value parameters. For simplicity, we place two restrictions on procedures. (1) Non-local variables are not allowed to appear in any procedures. (2) All parameters of procedures are of integer type. We have attempted to make the proof rules clear, understandable, and easy to apply to program verification. Our proof rules are readily used to aid in generating verification conditions in mechanical verifiers. We present several examples so as to show how these proof rules can be used to facilitate varification of programs with procedure calls.
