Hi,
I seem to remember that it was possible to save a FORTRAN IV program
together with the FRTS runtime system as a runnable .SV core image
file. It seems that ADVENT does so...
Any idea?
That's the older version of OS/8 Adventure - it initialized then exited
to OS/8.
Unfortunately, the source for that has been lost, and I don't remember
how it worked.
I think it repeated the "PDPXIT" entry point in FRTS, didn't close
units, then exited. Upon restore, it re-enabled interrupts and continued.
(minor question: How does something like "R PROG
ARGS" work?)
Again, too long ago, but IIRC this uses the CHAIN entry point and uses
known data (command buffer in field 1 loc'n 1200), etc. to read and
parse the additional args.
