The limit may have increased since then - although I would never want
to go above 3 or 4 anyway so I have never felt the need to check.
The service program limitation is a little restrictive - they should
probably raise that if only to accommodate existing procedures that
have more than that. I _think_ the limits arise from the Java
tooling rather than IWS itself. David might know the answer to
that.

Yes, the API that's used to invoke service program procedures (QZRUCLSP) has a limit on the number of parameters that can be passed

The procedure parameters are passed as pointers via the API.

Up to 7.2 the limit was 7 parameters. https://ibm.co/3yUWSKV

As of 7.3 the limit is 248 parameters. https://ibm.co/3jV3FOs
