110741 VLOAD: A Program for RT-11 Extended Memory Monitor

28KW of memory Keywords: System Management - RT-11, Tools -

Abstract: This is a program for the RT-11 Extended Memory Monitor.
It
is an extension of the RT-11XM keyboard command FRUN (and
SRUN). The purpose is to run an un-overlaid virtual
foreground (or system) job with 32KW of user memory. As a
result, it only takes up 4KW in the background (kernal mapped
memory) job's space and makes the most of the extended
memory. In the example, BASIC-11 is used to show the
installation procedure. Full featured BASIC-11/RT-11 takes
up 12 KW and will end up with 20 words user memory.
Notes: This program will need to be adapted to each use and should
be installed by someone with MACRO-11 experience. FORTRAN or
MACRO programs may be used instead of BASIC-11.
Restrictions: RT-11 time of day feature doesn't work. All
restrictions of
virtual jobs apply; e.g. no interrupt routines; no access to
Kernal Mapped Monitor Memory; I/O page not valid unless
explicity mapped; MRKT requests won't work.
Media (Service Charge Code): One RX01 Diskette (KA) Format: RT-11,
600' Magnetic Tape (MA) Format: RT-11
