In the static call the load module of the called pgm is linked with the calling pgm. While in case of dynamic call the 2 load modules stay separately.

In case of dynamic call the called pg can be used by many other pgms.

Static call Identified by call literal eg: call 'pgm1'

SUb-modules are link edited with the main module

If the sub-pgm undergoes any changes both the sub and main

pgms need to be recompiled.

Dynamic call Identified by a call variable eg: call ws-pgm

sub-modules are picked up during the run time from the load

library.

If the sub-pgm undergoes any changes it is sufficient to recompile the sub-pgm alone.

In a static call the call is done using a literal. Compiler option is NODYNAM
In a dynamic call the call is done using variable. Compiler option is DYNAM
