I added this to str1.asm to check if new filename exists
but it fails whether date named file is present or not.


there_already:   ; check to make sure that the file with the date format
                 ; isn't already there  

;       mov      dx,offset storage + 2
;       mov      ax,7143h           ; See if file exists
;       int      21h                ; carry flag set if problem
;      jc        short file_there

is_a_path:
       xor      ax,ax
       xor      dx,dx
       mov      ax,7156h                 ; LFN rename file  Win 98 +
       lea      dx, orig_name + 2        ; old name
       lea      di, storage              ; sets the new name
       int      21h

thanks.

jnc?

What's bl? I suppose you want 0 - that'll only trash cx. Why not 714Eh? 
The need to close the "handle"? How about just checking the return from 
7156h? (I assume it won't rename to an existing name - haven't tried it 
- should return CF and 50h in ax?)

Best,
Frank

P.S. I see you got crossposting working. Good!

That's not so good ...  What are the error-codes returned in both
circumstances ?   Maybe they will tell you what the actual problem is.

(thanks for using cross-posting)

I did respond but it was never posted. I don't know if it's my
IP or what. There are just two NGs where this is happening.

I was getting 2 in al for when the file was present. I will
get back to you SOMETIME when and if I get a chance.

I'm sorry to hear that.

You do know what error-code 0002h (in AX, not AL :-) means, do you ?   It
means "File is not found".

It probably means that you *think* you are checking for a certain file, but
you are not.  Most probably a wrong filename/path, or even looking for a
hidden file without specifying so.
