Execute magnetic tape" FILL" procedure for magnetic tape unit 0 (on the W
buffer for 900 Series Computers, or on Channel A for 9300 Computers). A
tape reel containing a MONARCH system tape must be positioned at load
point on tape unit 0 (on the W buffer for 900 Series Computers or Channel A
for
9300 Computers).
This program has been written so that it can be executed only if loaded rela-
tive to memory location 2. However, since a 1\ address references are abso-
lute, it can be loaded relative to any reasonable memory location prior to
being recorded on the system tape as an absolute program. No PROGRAMMED
