Hi Rob -
Other's have suggested the %parms method. Not bad. However it is possible to have parameters missing in the middle. For example I have an old program (that I wouldn't write that way anymore, but you may like since you're into old os's) that does a RTVJOBD. Now, remember on the RTV... command set you may omit parameters, right? Right there is a classic example of parameters missing in the middle. %parms is a worthless solution if you may be missing parameters in the middle.
Those parameters are NOT missing. They DO contribute to the %parms count. The difference is that the pointer in the parameter list for an "omitted" parameter is *NULL rather than being a valid pointer.
The *NULL pointer can be tested for in a regular RPGLE program just like it can in a procedure.
So if there is any possibility of "omitted" parameters as well as parameters not passed, both %parms *and* %addr need to be checked.
