Re: Processing a list of procedure parameters

["Rory Hewitt" <roryhewitt@xxxxxxxxx>]

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
