Duane,

Unfortunately, you can't always assume that a procedure's parameters are
always sequential. However, see this thread, which explains what you can do
with the NPM_PARMLIST() MI builtin.

http://www.systeminetwork.com/isnetforums/showthread.php?t=45802


(look at message #14 onwards). With this builtin, you can process parameters
in an argc/argv way. There are several code samples that Scott and I each
added.

Although it essentially discusses CONST parameters, you can process VALUE
parameters, but it's a little more tricky, since you'd need to retrieve the
data itself from the returned Argument field (using natural padding to
determine the start/end of each parameter).

Regards,

Rory

I am trying to build a procedure which will concatinate several parameters

parameter pointers (passed by value) are stored sequentially in memory.
This
looks to be as true in RPGIV as it is in C, (argv) so I set my array's
basing pointer to the address of the first parameter, the array elements
each contain the same address as the corrisponding parameter, as I would
expect, but I am only able to access the first parameter's data through
the
array either in the compiled code or with the debugger.
The code is at: http://code.midrange.com/index.php?id=9356ecdb93

How do I work around this?
Is there a way to process parameters as a list in RPGIV, rather than
individually?
