Initialises the PCG RAM and prepares BASIC to receive SET,RESET,PLOT etc. commands. The screen is not cleared by this command and any UNDERLINEd or INVERSE characters will be replaced by rubbish characters.
The code 128 may not be used, since this is internally used to signify end of string. Equivalent to, and usable for 128, are the characters 32 (space) or 192 (Graphics blank).
Program Example.
00100 CLS
00110 LORES
00120 FOR C = 129 TO 192 : REM print all graphics codes
00130 PRINT CHR$(C);
00140 NEXT C
00150 END
