Re: CallP Versus Program 'CALL'

If you talking about performance of CALL vs CALLP both making a program
there should be no difference at all. CALLP is just interpreted by the
compiler to generate CALL or CALLB code based on what you are calling.

Having said that, you should not be doing either one. CALL, CALLB and CALLP
are all obsolete. What you should be doing is prototyping the program
calls.

d CreateBFile...
d pr ExtPgm('ABCPGM')
d PR_CustomerNumber...
d 8a Const
d PR_Amount...
d 7p 2 Const
/Free

CreateBFile('A0001':
12.50 )

/End-Free

And, of course, if we push it up to the next level, if we are building new
code we shouldn't be doing program calls. We should be encapsulating our
business logic in service programs and making procedure calls.

My apologies Alan, I should have said CALLP, I knew what I was trying to
say :) I just didn't make it real clear and I appreciate your picking up
on that! Next homebrew beer is yours :)

Assuming I am understanding you, a CALL is not a procedure call, it is a
program call.

Making a procedure call is thousands of times faster than making a

program

call whether that procedure is in a program or in a service program.

Program calls have gotten faster but they are still very slow compared to
procedure call.

I was recently reading that a static procedure call is faster than a
typical program CALL.

I know that with procedures you can pass more data (Parms if you will)
than you can with a typcial program CALL, but are locally or externally
defined procedures really that faster than program CALLS?
