RE: Program Call Parameters

["Kumar, Santha" <sankumar@xxxxxxxxxxxxxxxx>]

Making my old RPG Programs modular is not an easy task for me. It involves
analysis and redesign of all functions within it. We all know that the Java
methods don't have that many parameters. But my question was about how to
use the AS400 Toolbox Java ProgramCall class to call an "Existing old RPG
program". 

Thanks Richard for the "structure" solution.

-|Have you ever seen a Java method with 35 parameters?

No and it sounds horrible.  Why do you want to have so many?

-|Better design -- for a monolithic program.  My company's "pricing -|black
box" program is designed in just this way, and had over 60 -|parameters last
time I looked.

I did not prescribe the number of parameters or tell the OP that he should
or can break it down.  Maybe he cannot have fewer parameters for his
existing design and cannot change the design.  Maybe he has to do it this
way now then go back later and do it correctly.  Would you have me tell him,
"F**k off, you can't do it and you're stupid to try"?   Or should I give him
the best solution within the stated parameters?

What is your problem?

-|create a structure, copy the data into the structure, call the RPG program
-|with a pointer to the structure.  One parameter - better design.

-|-|Hello,
-|-|
-|-|The program call class in JT/400 allows a Java program to call an
-|-|AS/400 RPG
-|-|program. However there is a maximum restriction of 35 parameters.
-|-|One way to
-|-|overcome this limitation of 35 parms is to call a stored procedure which
-|-|then calls the RPG Program. Is there any other easy way to directly call
-|-|those programs that have more than 35 parameters ?.
-|-|
-|-|Thanks in advance
-|-|
