The relevant code is: 2000 POKE 559,0:DIM S4(1024) 2010 A=ADR(S$):B=INT(A/512+1)*2:CBASE=B*256-A+1 2020 FOR I=0 TO 511 2040 S$(CBASE+I,CBASE+I)=CHR$(PEEK(I+57344)):NEXT I:H=16:V=23 The poke 559,0 blanks the screen and it never comes back. If I leave the poke out then I get an error message at line 2040 that there is no FOR associated with the next. Can anyone see anything wrong with the code here? It checks out using computes checksum program, but it doesn't run. Aftyer typing in 11 blocks of code I sort of want the thing to run now. This is on an 800XL. Any help would be greatly appreciated.
