Hi,
This is just to add little more description to Niki's
answer.
FETCH: This comes in 2 forms.
FETCH 'program' is just like the CHAIN in COBOL, where in
the control does not come back to the calling program.
With Fetch there can be parameters passed to the called
program.
FETCH RETURN: Similar to FETCH, but the control will
comeback to the calling program. Like the CALL statement in
COBOL.
CALL: Calling the non-Natural programs and the control will
come back to the calling module.
CALLNAT: Calling sub program with/with out parameters.
