Re: User defined commands with a "choice program"

[Vern Hamberg <vhamberg@xxxxxxxxxxxxxxxxxxxxxxxxx>]

In the hope of teaching someone "how to fish" - AS/400 commands are built 
with standard components - DSP for 'display' and FLR for 'folder', etc. 
These components are documented in CL Programming manual.

Appendix E. Abbreviations of CL Commands and Keywords
This section contains alphabetic lists of abbreviations that are used in CL 
commands that are part of IBM OS/400 and other IBM AS/400 licensed 
programs. This information can assist you in naming commands and keywords 
in a consistent manner when using command definition.

So, to display the contents of a folder, try DSPFLR. It has an *OUTFILE 
option, so can be read in your choice program.

Knowing these abbreviations is useful, too, in looking for commands for 
object types or actions. Thereare many menus that list commands, and they 
all start with CMD, followed by one of these abbreviations. Commands about 
folders can be seen using GO CMDFLR.

But it probably won't work - the choice program only gets passed the 
command name, the parameter name, and a type character, 'C' or 'P'. The 
values of parameters are not available, AFAIK.

Of course, you could use a choice program to display all folders, then pass 
back selected folder. Still, this does not fill in the parameter, only 
shows a list of values. Also, it does not do any validity checking. You'd 
need to have some mechanism in the validity checker to do this.

Or use the exit program facility for commands, which comes in prior to the 
rest of command processing.
