procedure declaration. The correspondence is established by the positioning of the parameters in the lists of actual and formal parameters. Parameters provide a substitution mechanism that allows a process to be repeated with a variation of its arguments (e.g., MinMax is activated twice to scan array A and once to scan array B).
