Peek and Poke?

[OB1]

Is there a way to perform low level memory functions in basic? Is it the peek and poke commands that I saw somewhere?

[Koralt]

Use the PEEK function to read a byte from memory, and POKE to set one. To set the Data Segment (DS), use DEF SEG

Example:

DIM I AS LONG, CL AS INTEGER

SCREEN 13  'VGA mode 19:  320x200 256 color

DEF SEG = &HA000 'Point to VGA memory

FOR CL = 1 TO 15
  FOR I = 0 TO 63999
    POKE I, CL  'Set each pixel ...
  NEXT I
NEXT CL

DEF SEG 'Restore the default

Yeah. That should work ...

Thanks for the help.

or get powerbasic and use pointers which are quicker.
