== Why is this an issue? Prototypes should be used for program calls because their use allows compile-time checking of the number of parameters and the type and size of those parameters. Without the use of a prototype, that checking happens only at run-time. A secondary benefit of the use of prototypes and ``++CALLP++``, is that prototypes allow the caller to gain a clearer understanding of the data expected for each parameter because parameter names are purely descriptive. === Noncompliant code example [source,rpg] ---- ---- === Compliant solution [source,rpg] ---- ---- ifdef::env-github,rspecator-view[] ''' == Comments And Links (visible only on this page) === duplicates: S2202 === is related to: S2202 endif::env-github,rspecator-view[]
