Subject: Re: Input from command (was blank subject) 


Why not simply define the input parameter as a data structure like this:

      D BndSrvPgm_t     ds                  qualified based(template)
      D   SpCount                      5I 0
      D   BndSrvPgm_                  10A   dim(32767)

      D MyPgm           pr                  extpgm('MYPGM')
      D   BndSrvPgm                         likeds(BndSrvPgm_t) const
      D MyPgm           pi
      D   BndSrvPgm                         likeds(BndSrvPgm_t) const

If you do that, you won't have to use %subst() in a loop to move it to
an 
array, and you won't have to worry about dynamically allocating memory. 
(The command will, however, dynamically allocate only as many elements
as 
needed, so make sure you don't try to use any past the number in
SpCount)
