RE: is nmi translator off limits?

Do you mean that all systems should be static? That all possible parameters of all service program functions

are decided before any programming is done? This is certainly not the case with the applications I know.

We have live and everchanging systems reflecting the changing needs of the companies using them and

their customers.

 

Do you mean that every time a new parameter is needed to a service program function I should invent a new

name (eg. GetListOfCustomers37)?

 

Since we're quite off topic here, maybe we should discuss this in the AS/400 NG? :) It would be interesting to know

if I'm out on my own here...

what you describe does not scale up to 100s of programs

maintained by dozens of programmers. No matter how smart

you think it is, it's not worth it.

If I can reuse a function in a service program by adding another parameter, which is (presently) not needed

in any other program, I think it's good from a maintenance point that I don't have to change and recompile

all programs that use the old version of the service program. Isn't this what the version stamping of service

programs are meant for?

 

If I have to make changes to programs using the old parameter list, I can change them to the *CURRENT

*SRVPGM function parameter list at that time. Depending on how the parameters are specified I will or

will not get a compiler error message stating that the call doesn't match the prototype.

With a service program I can change the parameter list to an existing function, or let a completely different

function (with a changed parameter list) take over the name of an old function; and still let old programs

using the old function work without modification or recompilation. How would you accomplish this with your

CallM opcode?

 

===> I don't think what you describe is even desirable. what a maintenance nightmare.
