Hi,
The FreeDOS wiki says that NASM is the reference assembler. However, when I use FreeDOS DEBUG to disassemble (unassemble?) a com file, the syntax for addressing memory is not NASM syntax. C:\ASM>debug psp.com -u 100,118 0A27:0100 BB8000 MOV BX,0080 0A27:0103 3E8B0F MOV CX,DS:[BX] 0A27:0106 30ED XOR CH,CH 0A27:0108 43 INC BX 0A27:0109 E80200 CALL 010E 0A27:010C CD20 INT 20 0A27:010E B40E MOV AH,0E 0A27:0110 3E8A07 MOV AL,DS:[BX] 0A27:0113 CD10 INT 10 0A27:0115 43 INC BX 0A27:0116 E2F8 LOOP 0110 0A27:0118 C3 RET - As opposed to: MOV BX,0x0080 MOV CX,[DS:BX] XOR CH,CH INC BX CALL 0x010E INT 0x20 MOV AH,0x0E MOV AL,[DS:BX] INT 0x10 INC BX LOOP 0x0110 RET This might be a little off topic, but when I try to reassemble it, NASM gives the error: 11: error: short relative jump outside segment 11: error: short jump is out of range Sorry if this is a bit off topic Jeffrey ------------------------------------------------------------------------------ AppSumo Presents a FREE Video for the SourceForge Community by Eric Ries, the creator of the Lean Startup Methodology on "Lean Startup Secrets Revealed."
