I've been working on something and wanted to be sure I was doing this part correctly. I put this into Debug (didn't crash, didn't work) and NASM for Windows and it didn't work (tmp.asm:5: expression syntax error).
MOV AH, 0B
MOV BL, 02
MOV BH, 01
INT 10
MOV AH, 10
MOV AL, 03
MOV BL, 00
INT 10
MOV AH, 0A
MOV AL, 57
MOV CX, 01
INT 10
RET
after that I tried to assemble this (Debug sucks):
MOV AH, 10
MOV AL, 03
MOV BL, 00
INT 10
MOV AH, 0A
MOV AL, 57
MOV CX, 01
MOV BL, 02
INT 10
RET
and it gave be the same error but with 5.
I was trying to just output a light green (I like to call it Matrix green or Tron green) capital W. For this project, I'd have to use a BIOS interrupt, otherwise I'd go with DOS INT 21.
When I get this help, I'll definitely be able to continue immediately and will then post the code and whether it worked or not.
yes, it's a surprise 😁
