Re: VM/370 CE - Editing an APL function
The code I started with is available here:
That code ran in a special environment in OS/360. The runtime environment from OS/360 was not included.
You have to agree not to redistribute the source, to get a copy.
I built a runtime environment on VM/370 to use that code. I made it work on a VM370 3270 with the APL support available for that device.?
I don't remember any linemode 2741 support being available in VM/370. If you know where it is, please show me.

Are you saying that CP has no 2741 support? Someone must have taken it out. The 2741 was a mainstay of VM/370 when it was in its prime.
I'm also puzzled about how APL\360 got 3270 support. Certainly the code as it came from IBM didn't have it.

True. Our VM/370 has no linemode terminal support for a 2741. Bob Bolch
What you wrote is reported in the GC26-3847 manual from 1975 but it doesn't seem to work with the version of APL available to us

?page 88ff describes function editing in APL\360.
Seems to work with slashes under the current line.?

Re: VM/370 CE - Editing an APL function
e.g. [delta4] where delta is the APL delta sign (on key D) would delete line 4 of the current function.
to open the editor use the nabla operator.
eg.
nabla TEST []

deltaN in square brackets deletes a single line in the APL del editor.
Hey Dave,
I remember it is possible to edit APL functions on a full screen 3270 with APL support, but I haven't looked at it in years. I will look into it this week.
Bob
Bob,
Is there a way to delete a line then?
Dave

?
The version of APL360 that I made available only has support for PCOMM?and the Blue Zone
3270 emulators with their APL features. There is no support for any line mode terminal emulation.
?
I downloaded and installed the version found in this group.
With PCOMM and the APL keyboard (ctrl-F8)? everything works except what I have already said.
I'm pretty sure I read that using a 2741 device emulated with Hercules causes abend in VM/370.
If there is any news on this, I would be grateful to hear about it.

Re: VM/370 CE - Editing an APL function
Hm. I should try it with my 3279 S3G-1, which has the APL ROS in it (but not an APL keyboard).

Re: VM/370 CE - Editing an APL function
Correct, APL did not initially support 3270's as these did not
yet exist.
You needed a 2741 terminal attached via start/stop line.? I know
this because my first IT job (early 70's) was in Poughkeepsie with
a company that offered time sharing services using APL to
not-for-profit organizations, usually schools.? How exactly this
is configured with Hercules I have no idea.? There was work done
on the Hercules 270x emulation (the mainframe end point of the
start/stop telephone line) for APL.
What I am saying is, APL will work as described in the Primer on
Hercules.? Will APL work under VM?? Do not know.? Whether support
within APL existed for a system console (which you are using) to
be a terminal that could edit APL is unclear to me.? Rather
doubtful.? Entirely different character set.
Never actually worked in the data center in that job so do not
know the system end.?? I do remember that APL was run on DOS and
later they moved to DOS/VS.

I am following what is printed in the
APL\360 Primer book.
To delete a line (i.e. #3)
[3] press the ATTN key, followed
immediately by carrier return.
1) is carrier return some 2741 key that
PCOMM 3270 emulator doesn't have, or is carrier return to
be intended as carriage return?
2) if I press ATTN and CR I find myself
at the CP prompt, how is it possible to return to my APL

Thanks for any suggestions, I'm not at
all knowledgeable about the VM/370 system.

Yes, by entering BEGIN you return to the APL session but the line to be deleted is sitll here.
