Hello,
In IBM documentation on the description of possible commands in the CEDA, I stumble on the distinction between the commands DISPLAY and EXPAND. I do not see too subtle!
and3.2.8 The CEDA DISPLAY command
Display one or more group names, list names, or resources on a full screen panel.
If you're asking this type of question, you would be well advised to find a copy of this manual for your version of CICS and read it cover to cover.3.2.9 The CEDA EXPAND command
Show the resource definitions in one or more groups or lists. This command has been retained for compatibility with previous releases.
