whats wrong in he followin lines.

	ja Label401061
	cmp eax , 0C000008Dh
	jb Label401080

Label401025:; < line 43
	mov esi , 01h

Label40102a ::
	mov  dword ptr [ esp ] , 08h
	xor eax , eax
	mov  dword ptr [ esp + 4 ] , eax
	call Fun4163b0

I get the following error:
kaillerasrv.txt(43) : error A2108: use of register assumed to ERROR
kaillerasrv.txt(46) : error A2108: use of register assumed to ERROR

Thanks in advance

I may be wrong, but in the assemblers I've used, labels are defined as follows:

(Toggle Plain Text)

.MyLabel

By the way, try using descriptive names for your labels, as opposed to seemingly-random numbers.

DaWei · Nov 21st, 2005, 10:15 AM

Many assemblers also use the

Label:

approach. Not seeing line numbers isn't a huge help to potential respondents. Have you actually checked your documentation to see what A2108 has to say about itself?

EDIT: Ahhhh, my curiosity is going to kill either me or my cat.

The "ASSUME register:ERROR" syntax causes the assembler to
generate an error if <register> is later used explictly or
implicitly. The OPATTR, .TYPE, and TYPE directives do not cause
errors when referring to registers assumed to ERROR.

hehe...It better be your cat DaWei

How do i fix it?? I tried ASSUME register:NOTHING with all the registers and it doesnot work

*masm detects .MyLabel as being a syntax error.

I'm not really up to speed on this, rsnd. Why don't you zip your file and attach it to a post (or, post it directly if it's not too large). I'll clobber the cat with it and see what meows. If Lostcauz happens to peep in, his crystal ball will handle it, no doubt.

The crystal ball tells me the code in question is missing the .code section.

Scorpions4ever · Nov 21st, 2005, 7:39 PM

Try:
mov esi , 00000001h
instead of:
mov esi , 01h

and also:
mov dword ptr [ esp ] , 00000008h
instead of:
mov dword ptr [ esp ] , 08h

LOL. Some balls, Randy.

This is driving me nutz.
