Ah, for my previous post, I forgot you were already using RPG.  With
your current setup, if you define parm01 etc as 1A, you could use this
prototype and select statement to do your calls.  If you rename the
parms you're passing to p01, p02, p99, you can cram more parms on each
line.

D pgm          pr          extpgm(program)
D   p1                 1a  options(*nopass)
D   p2                 1a  options(*nopass)
D   p3                 1a  options(*nopass)
D etc
D   p99                1a  options(*nopass)
 /free
    select;
      when numparms = 0;
        pgm(); 
      when numparms = 1;
        pgm(p01); 
      ... etc ...
      when numparms = 99;
        pgm(p01:p02:p03:p04:p05:p06:p07:p08:p09:p10
            ... etc ...
            p91:p92:p93:p94:p95:p96:p97:p98:p99);
      endsl;
