Dynamic/static call

Postby maxcc » Sat Jul 10, 2010 12:17 am

How can we find out in a program if it is a dynamic/static call apart from dynam/no dynam option?

The best way is to look at the load module using AMBLIST or whatever similar tool your site uses to see if the called program is linked into the load module.

The static form of the CALL statement specifies the name of the subroutine as a literal; e.g., it is in quotes.



The dynamic form of the CALL statement specifies the name of the subroutine using a variable; the variable contains the name of the subroutine to be invoked


Plz revert if you need more info.

Hello,

While that is somewhat true, the best way to see how a module is invoked is using AMBLIST as Robert suggested. . .
Hope this helps,

Your statement is not true all the time. From the COBOL Programming Guide manual:
2.4.20 DYNAM

Use DYNAM to cause nonnested, separately compiled programs invoked through the CALL literal statement to be loaded for CALL, and deleted for CANCEL, dynamically at run time. (CALL identifier statements always result in a runtime load of the target program and are not affected by this option.)
So a statement in the form of CALL 'ABCDEFGH' may be static OR dynamic, depending upon the compiler options used.
