REQUIREMENTS:
SUBROUTINES
USED:
a. The magnetic tape search subroutine ($QSRCH). This subroutine
is used by the loader, and by the MONARCH Monitor routines,
to locate files on magnetic tape. Specifically, it is used by the
loader to locate the MONARCH Library on a MONARCH system
tape.
b. The Monitor Bootstrap {$QBOOT}. This subroutine is used by the
MONARCH Control Routine and the various MONARCH system
routines to initiate reloading of the MONARCH system tape (see
Section 2 of the MONARCH Reference Manual).
c. The three input subroutines ($QCARD, $QTAPE, and $QPAPER)
used by the loader to read binary records. Bits 9 through 23 of
QSYSIN must contain the address of one of these subroutines
when control is relinquished to the loader. Bits 9 through 23 of
QSYSTP must contain the value of QTAPE when control is relin-
quished to the loader. These are the only input subroutines ref-
erenced by the loader.
d. The dump routine ($QDUMP). This routine may be referred to by
MONARCH routines or by a user to dump memory in octal with
zero suppression.
