RE: ServiceProgramCall - use parms for output too?

I found out what my problem was.  For the output variable in the parm
list I needed this:

parmlist[1] = new ProgramParameter(30);

...Instead of this...

parmlist[1] = new ProgramParameter(new AS400Text(30,
as400).toBytes("output")); 


I am now able to get a value back in the second parm.  I am not quite
sure why this works, but it works.  I think the Toolbox developers have
some assumed implementations that aren't readily apparent by just
looking at the classes.

Here is the working code for anybody else that might run into this:

     P CallRPG_var     B                   Export
     D CallRPG_var     PI
     D  pInput                       30A   Const
     D  pOutput                      30A
      /Free

       pOutput = 'It is working yahoo!';
       Return;

      /End-Free
     P CallRPG_var     E
