I am new to rexx. I need a help to develop a tool -
purpose of the tool:
to open the dataset in view or edit mode while handling in jcl itself.
(i.e) in jcls we have given dsn=datasetname while placing the cursor in dataset name and pressing function key it should popup a panel with view and edit option and performing the corresponding function related to it.

Check out file 671 on the CBT tape (http://www.cbttape.org) which is described as

ZOOM edit macro to "cursor retrieve" datasets

Why waste the time writing your own tool when there already is something to do pretty much what you want to do already?
