Thank you for the info. It turns out that there is a limitation of 7 parameters calling a service program using the Java toolbox. This seems ridiculous but below is the reply given to a colleague from IBM support.

You this but you cannot call a service program with more than 7 parameters. This isn't really a java toolbox limitation, but a limitation on the QZRUCLSP (call service program) API =
which is documented here:

The toolbox ServiceProgramCall is just calling this API so it is subject to the limitations of that API; therefore, you are only allowed to use 7 parameters to a service program call.

COBOL is 255:

CL is 255:
Look up CALL in the command finder:

Therefore, I would limit my C/C++ programs to 255 to be safe. If the procedure is statically bound and called i.e.: (CALLB) you can go as high as 399 for ILE RPG and ILE COBOL. CL (CALLPRC) is limited to 300.

What is the maximum number of parameters on a C program call on the IBM i system? We are at V6R1. Is there a documentation link that someone can point to that notes this?
