Hello all, i am having trouble with a FindFirstFile int call, isn't that supposed to put the file name 1E offset to 80h in a com file ?? Or i am in a illusion that i can use this interrupt under win xp ?? Or it may be the fact that in windows it isn't put under DTA... is some one kind enough to point direction ??
Here is the code, i am trying to print the file name of the first matched file.
c_seg segment 'code'
org 100h
assume cs:c_seg
main proc far
start_:
mov ax, cs
mov ds, ax
mov es, ax
file db "*.com", 0
mov ah, 4Eh
mov dx, offset file
mov cx, 0
int 21h
jc quit_
mov cx, 13
mov bx, [80h + 1Eh]
loop_1:
mov ah, 02h
mov dl, byte ptr[BX]
inc BX
int 21h
loop loop_1
quit_:
mov ah, 4ch
int 21h
main endp
c_seg ends
end start_
compiling with
tasm /m file_name.asm
tlink file_name.obj
exe2bin file_name.exe file_name.com
