Introduction

C version of the RPG prpgram DSPINFO. This program works differently to the RPG version. I coded it to return only one field or constant at a time. So to see all the fields in a DSPF it needs to loop.

DISPINFOC is coded quite inefficiently but it still works quite fast. It retreives the API data for every time it is called then iterates though all the fields. I coded it this way so as to hide the API retreival within DISPINFOC.

The 2 versions below are more efficient.

I did not include any of the logic to retreive FILE, RECORD, or FIELD attributes. Also there is no logic for any other caterories (eg Date/Time) other than Cat 23 (Conatants)

DISPINFOC2 Version with C Module

I needed to drive this fron a CLLE (code is below) because I need a RCLACTGRP DISPINFO2.

Reason is I did a return from the C module, rather than an exit.
