You are right.  The (zip) file attachment was stripped 
by the list. Previously I posted the file (scanned image) 
as such.  As the file size exceeded 10 kB, it was rejected
by the moderator. 

I shall try to elabarate my problem.  I want to typeset the 
following gamma function:

[gamma of (l) gamma of (m)  gamma of (n)] 
divided by 
[gamma of (1 + l + m + n) ]


My crude attempt was
\newcommand{\gf}[1]{\vert\!\overline{#1}}
\[
\frac{\gf{l}\gf{m}\gf{n}}{\gf{1+l+m+n}}
\]

But the result is not satisfactory.
Please help.
Thanks in advance
