Program Loading
The program is assembled with device address OOE as the
output device. If this device is acceptable and available as
an output device, it is only necessary to
WL
the SEREP
deck from the card reader. The output device may be
changed in two ways:
1
Punch the address of the desired output device in
columns 67,68, and 69 of the last TXT card (next
to the last card in the SEREP deck).
::111
80
OR
2
1403 N1 PRINTER
(ADDR ESS OOE)
Reproduce this card, but leave these columns blank.
In this case, SEREP goes into the wait state after
loading. By causing a not-ready-to-ready interrupt
on a device (or by operating the REQUEST key on
the P R - KB), that device is assigned as a output device.
No other operator action is required.
