Printing Numbers and Clearing the Screen with ROM Routines

ZX Land #01

Displaying values

Displaying numeric values is done by opening a channel for the PRINT command, and then:

CALL #2D2B
CALL #2DE3
RET

Clearing the screen is a jump to the address:

CALL #0D6B

Next month

  • We’ll increase the size of our magazine (this issue takes up only half the memory)
  • We’ll publish a description of DIZZY V !!!
  • The next part of the description of ROM procedures
  • More POKEs
  • And 1001 other curiosities

As I close this debut issue, I’d like to ask you once again to send all your comments, suggestions, etc. to the editorial office:

Amen
