Calling the subprogram indirectly

Indirect subprogram call, CALL
Depending on the prevailing conditions at a
particular point in the program, different
subprograms can be called.
The name of the subprogram is stored in a variable
of type STRING. The subprogram call is issued with
CALL and the variable name.
The indirect subprogram call is only possible for
subprograms without parameter transfer.
For direct calling of the subprogram, store the name
in a string constant.
Example:
Direct call with string constant:
CALL "/_N_WCS_DIR/_N_SUBPROG_WPD/_N_PART1_SPF"
Indirect call via variable:
DEF STRING[100] PROGNAME
PROGNAME="/_N_WCS_DIR/_N_SUBPROG_WPD/_N_PART1_SPF"
CALL PROGNAME
The subprogram PART1 is assigned the variable
PROGNAME. With CALL and the path name you
can call the subprogram indirectly.
