Use in Direct mode (NAS-SYS U command).
As NAS-DIS asks for memory addresses, unpredictable things may happen to the
printer. This is because the subroutine outputs an ESC code, which the printer
takes as the start of a control code. The cure:
– Either turn the printer momentarily off when NAS-DIS signals “Go?”
– Or change these memory locations in NAS-DIS:
CD00 00 NOP
CDO1 00 NOP
CD02 00 NOP
Change printer reflection:
0F04 DF 4C C9 SCAL "L RET
ZEAP U command will now list the source file, and ZEAP A command will, with
option 04, give assembly listing.
Use in direct mode (NAS-SYS U command). It is possible to turn printing on and
off from BASIC with DOKE statements:
Printer on – DOKE 3187,1912
Printer off – DOKE 3187,1913
