The SubProc(SU) command runs one procedure from within another procedure. It performs the same function for a procedure file as a GoSub statement does for a program. This command can be issued by a program via the EXECUTE or CHAIN statement. For more details see the CHAIN statement.
Comments and Examples
BR suspends the originating procedure when it finds the SubProc command in a procedure file. All active procedure files remain open and BR executes the entire sub-procedure before returning control to the originating procedure. Up to 9 levels of procedures may be nested.
The following example starts execution of the SAMPLE procedure file:
SubProc B:Sample
Syntax
SUBPROC <file name>
Parameters
SubProc requires the file name parameter, which specifies the file to be executed as a sub-procedure.
