Setting implicit declaration of variables

The IMPLICIT-DECLARATION operand of the SET-PROCEDURE-OPTIONS command is used to specify whether simple variables can be declared implicitly. The default setting is IMPILICIT-DECLARATION=*YES. This means that simple variables can be implicitly declared when they are first assigned, without having to be explicitly declared with a DECLARE-VARIABLE command.

If the setting is IMPLICIT-DECLARATION=*NO, simple variables must be explicitly declared.

Complex variables must always be explicitly declared. Further details on this will be found in chapter “Using variables in S procedures”.
