Hi Rob, et.al. - >I am glad that you are using the if %null instead of %parms. >I was going to suggest that technique. One of my earliest >RPGLE programs uses this technique because I have many >parameters, of which few are rarely requested. Here's the >command that calls the program: Be very careful of using *null _instead_ of %parms. If the program will _ever_ be called with less the full number of defined parameters, %parms needs to be checked _before_ checking *null. As was discussed in a previous thread, valid pointers can be hanging around from previous calls, so just checking for an address not equal to *null does not guarantee that the parameter was passed on this call. Rob, in the case of your command processing program this was not an issue as all parameters are always passed to CPPs, *null as needed. Ken Southern Wine and Spirits of Nevada, Inc.
