搁别苍é,
Thanks for your kind answer. I'll try it today.
I'm a member ot the old yahoo group since about 11 or 12 years, but now I can't see the messages. This groups were much usefull to me, specially the LTspice.
One of my goals in managing tapes is install SPICE, an electronic simulator from the early 60's, still used today, but with graphical interfases like LT SPICE, that can generatee text lists that I think can be processed in mainframe spice.
One Of the things I was thinking about, was doing some control task on an IBM Mainframe. I know this boxes are batch processors, with very poor communications and task management, but an IBM360 worked as a realtime computer during the Apollo missions, so t can be done.
May be I can handle to comunicate with a seudo terminal using telnet. This terminal may be an arduino and can handle all the hardware input/output. in the mainframe a job may communicate using some text protocol like Modbus ASCII, that can be handled under 80 characters, and can be get in c format.
An issue is how to run a task each, let's say a second, withoug getting into making a new O.S. PL/I has a DELAY() builtin, but it's not implemented in MUSIC, I managed to fake a DELAY, using the system TIME, But I think MUSIC does not switch tasks upon time, but on I/O function ( in the 70's I stalled for 15 minutes an IBM/370 with VM-CMS, doing a fortran thermal analysis using parcial differences, because it was pure calculus and no I/O).
Regards. Carlos
