Hi everyone!
I need help in 58th func. So the standart RUN func. is:
mov eax,58
mov ebx,fileinfo
int 0x40
;=======data=======
fileinfo:
dd 16 ; - exec prg
dd 0x0
dd 0x0 ; - params
dd 0x0
dd 0x10000
db ’/HD/1/MENUET/APPS/FIRE’,0
;=======end of fileinfo

But I need to execute programm, but the path is integer - for example:
path_to_prg db ’/hd/1/meos/apps/fire’
and params too:
parametr dw 0
So the quastion is: What changes do I have to make to fileinfo to make it work Smile

(and do I have to add ",0" to the end of path? how?)

The path isn't an integer, but a string.....

fileinfo:

dd 16 ; 16=START APPLICATION
dd 0x0 ; nop
dd param ; 0 or parameter area ( ASCIIZ )
; receiving application must
; reserve a 256 byte area
dd 0x0 ; nop
dd 0x10000 ; work area for os - 16384 bytes
db '/HD/1/MENUET/APPS/FIRE',0 ; ASCIIZ dir & filename

ret: eax = pid or 0xfffffff0+ for error

According to this, it SHOULD work Smile

Maybe you have the same problem as me!
check out is that one works:

Code:


  mov eax, 58
  mov ebx, fileinfo
  int 0x40

     fileinfo:
   
     dd   0                    ; 0=READ    (delete/append)
     dd   0x0                  ; 512 block to read 0+
     dd   0x16                  ; blocks to read (/bytes to write/append)
     dd   0x20000              ; return data pointer
     dd   0x10000              ; work area for os - 16384 bytes
     db   '/HARDDISK/FIRST',0  ; ASCIIZ dir & filename

then you check the values at 0x20000 (for instands via a text-box), if there are strange signs, you also have 'my' bug
