Dear list,
I have the following sample code:
\starttext
   \startTEXpage[offset=1dk]
   \dostepwiserecurse{2}{6}{1}{\edef\AbC{\recurselevel}%
   \dostepwiserecurse{2}{7}{1}{%\AbC.\recurselevel\ /\
   \ifnum\AbC < \recurselevel%
   \AbC:\recurselevel\ \|\|
   \fi}
   \\}
   \stopTEXpage
   \stoptext
I would like to only get the numbers in the form first:second loops if
and only if the value of the first loop is less than the value from the
second loop.
I think this should be simple, but I don’t get it with any of these
conditionals:
\ifnum\AbC < \recurselevel
\ifnum\recurselevel > \AbC
Sorry for the stupid question, but what I am missing here?
Many thanks for your help,
These % after the comparison make tex scan on for the end of a number (a 
\relax of space ends the scan). You can do this:

\starttext
\startTEXpage[offset=1dk]
\dostepwiserecurse{2}{6}{1}{%
     \dostepwiserecurse{2}{7}{1}{%
         \ifnum#1<##1\relax
             #1:##1\ \|\|%
         \fi
     }%
      \\%
}
\stopTEXpage
\stoptext
