RE: Help needed for command lists within lists and RPGIV

["Tucker Gerry" <Gerry.Tucker@xxxxxxxxxxxxxxx>]

Buck,

Told you I wasn't charging on all cylinders today.  I always define
qualified parameters or lists in RPG as data structures, but I was
having problems defining the DS for this particular parameter.

It just didn't occur to me to check the incoming values in a long string
as an aid to defining the DS.

Worked it out now so many thanks for your help.

Perhaps the easiest thing to do would be to declare it a very long
character
field and use a data structure to map out the individual lists.
There'll be
a two byte binary "element count" in front of each list.  Dump the
character
field in hex and you'll see what I mean.
