I want to get the parameters in the command line in the DOS assembler.
I checked some information on the Internet. Probably it is said that the value of 80h in the DS segment is the length of the parameters.
I wrote the following small test program.
The length of the parameter can be obtained, but it is also possible to obtain parameters.
. Model small .stack 100h .datamsg db 13, 10, '$' .codestart: Mov Ax, @ Data MoV DS, AX; ------------------- --------- Mov Si, ES ADD SI, 80H MOV DL, [Si] MOV AH, 02H Add DL, 30H INT 21H
LEA DX, MSG MOV AH, 09H INT 21h; ------------------------------; below is the parameters A character's code can not normalize Add Si, 2 MOV DL, [Si] Mov Ah, 02H INT 21H; ---------------------------------------------------------------------------------- ------- Mov Ah, 4CH INT 21h End Start
