Yup - output *variables*. But I am puzzled by the notion of "output arguments". The Rexx language has no such notion. I realize I can mark arguments (as well as variables) as "output" on the AXREXX call, but that doesn't explain to me how they are mapped. The doc says "For the REXXARGS parameter, the entries mapped by AXRARGENTRY must appear in the same order as the arguments specified on the ARG statement in the REXX program", which makes sense on input. But I see no way for this to work on output - there is nothing to say I have to use Parse Arg (or short form Arg) at all, in fact I often use the Arg() function instead. Also Parse Arg can be issued more than once. So where does the interface get these output values, since it cannot always know what variables (if any) those values went into. If it is just saying that you can retrieve the value of some named variables upon output, then what is the difference between that and an output variable? > Have a look at the axrexx macro.

But I would rather have these things documented than have to tease everything out by experiment. Thanks...
