Editing APL objects with CMS XEDIT
Norman Brenner · ACM SIGAPL APL Quote Quad · 1984
The VM/SP System Editor XEDIT is used to edit APL objects. Two approaches are possible: with an APL function, or with an exec written in REXX (the new VM/SP System Interpreter). The advantages of the latter are that nothing need be copied into the user's workspace, and that APL code can be executed from XEDIT, and XEDIT commands from APL. No new Auxiliary Processor is needed. The technique is in use at IBM Yorktown.
