string manipulation

[the182guy]

is there any equivalent functions in assembly like the vb mid() left() split() etc etc?

There are no library functions in assembly

If you're using MASM there might be macros for it.

Hutch's MASM package i think includes some similar functions - but you have to include them into your program. Check the m32lib directory in the MASM package. - Yeah its there - SZLEFT.asm, SZMID.asm etc. then you just include them in your program.
However, these were written for compatibility and some i believe quite some time ago - so they are not fully inefficient

thanks I found the SZLEFT.asm, im trying to include it in the program, im not actually trying to call the proc yet, only including it, heres my code:

.486
.model flat,stdcall
option casemap:none

include \masm32\include\windows.inc
include \masm32\include\user32.inc
includelib \masm32\lib\user32.lib            ; calls to functions
include \masm32\include\kernel32.inc
includelib \masm32\lib\kernel32.lib

;left function !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
include \masm32\m32lib\SZLEFT.asm

.DATA

Message db "This is the message",0
Caption db "This is the Caption",0

.CODE

start:

invoke MessageBox, NULL, addr Message, addr Caption, MB_OK
invoke ExitProcess, NULL

end start

it just says 'make errors occured' btw that is the correct path to the file

BTW this is MASM

also...
could someone give an example of how to call it with an if statement so the pseudo code would be:

if left(addr Message, 3) == "abc"
     ;the first 3 chars are abc
else
    ;the first 3 chars are not abc
end if

thanks
