+% v1.0 1996/09/05
+% v1.1 1997/07/10
+% v1.2 1997/12/15
+
+
+% #1 is the name of a LaTeX counter.
+\def\commaform#1{%
+  \expandafter\@commaform\csname c@#1\endcsname}
+
+%     The token to place every three digits.
+\def\commaformtoken{,}
+
+% Internal version.
+% #1 is the number. It may be a TeX count register, eg \count@
+%    or an explicit number such as `1234'.
+% v1.1 use \relax not empty so explicit digits need not end with a space
+% token.
+% (This \relax will be eaten by the parser, second two must be \@empty)
+% v1.2 add \@comma@ux for very long digit strings (requested on c.t.t)
+\def\@commaform#1{%
+  \expandafter\@commaaux
+    \expandafter{\expandafter}%
+    \number\@comma@ux#1%
+    \relax\@empty\@empty}
+
+
+% If \@commaform is given a very long digit string then it may be
+% too large for \number, so make sure \number only applies to the first
+% token. This may leave a spurious space token, but it will be eaten
+% by the \@commaaux parsing, which uses non delimited arguments, and
+% so skips space tokens.
+% Added in v1.2.
+\def\@comma@ux#1{#1 }
+
+% Wander down to the end of the number and then see where
+%    \relax turns up.
+% #1 List of digits already seen (initially {} )
+% #2#3#4 next three digits (or \@empty) in list.
+\def\@commaaux#1#2#3#4{%
+  \ifx\relax#2%
+    \addcomma#1\relax
+  \else
+    \ifx\relax#3%
+      \addcomma\@empty\@empty#1#2\relax
+    \else
+      \ifx\relax#4%
+        \addcomma\@empty#1#2#3\relax
+      \else
+         \@commaauxafterfi{#1#2#3#4}%
+      \fi
+    \fi
+  \fi}
+
+
+% Get out of the nested \if before recursing down the list of digits.
+% #1 list of digits seen so far.
+\def\@commaauxafterfi#1\fi\fi\fi{%
+  \fi\fi\fi\@commaaux{#1}}
+
+% Go down adding a `comma' every three tokens. The list will have
+%    been padded with 0 1 or 2  \@empty at the start so there is
+%    definitely a multiple of three tokens before the \relax.
+% #1#2#3 are next three digits
+% #4 is next digit, or \relax to stop
+\def\addcomma#1#2#3#4{%
+  #1#2#3%
+  \if#4\relax
+  \else
+    \commaformtoken
+    \expandafter\addcomma\expandafter#4%
+  \fi}
