how to call subroutines in scripts
hi,
for calling subroutines in script form by using PERFORM --- ENDPERFORM control commandS..
/:PERFORM <name> IN PROGRAM <program_name>
/:USING <parameter>
/:CHANGING <parameter>
/:ENDPERFORM
while calling subroutine you must pass one parameter only for one line.
you mus specifies the program name in which subroutine is available.
while declaring subroutine, you must define subroutine formal parameters of type structure ITCSY, otherwise error will be raised..
FORM <name> TABLES <input> STRUCTURE ITCSY
<output> STRUCTURE ITCSY.
here write the logic...
ENDFORM.
regards,
Ashok Reddy

Hi
When you don't have option to change the driver program connected to the script, and when you wants to bring some external data from other tables and to do external calculations we use these subroutines in scripts
See the sample programs for calling subroutines
