The workspace (.BXWA from ~30000 to ~60000 bytes). It also contains a character set for
Vt220 for the APL character set.
When you install the APL task experiment with the /INC to maximize the available
workspace, On my system, I can
INS APL6.TSK/INC=37000 to max the workspace for the single precision version.
Also, the scanned APL-11 reference manual can be downloaded at
and the APL11 installation guide at http://www.rsx11m.com/APL11ins.pdf
The RSX SIG files that have the info to change APL-11 to an I/D RSX11M+ task from

According to the Ref Manual, that's the one I was looking for.
Now to mount the RL on RSTS and see what it takes to build it
there. I'll let the list know how I make out in case someone
else is interested.
Please let me know if I can help. I haven't done a whole lot of work with RSX origin
applications on RSTS but from what I know the process should in general be
straightforward. I don't think it's quite as easy as just running the .tsk file
(different RMS image) but reassembly and re-TKB with the existing control files feels like
it should be successful.
