\exitloopnow</code> instead. Beware, this is more sensitive
for conditional errors.
=== Recursion and expansion ===
Using recursion to build tables requires some particular attention:
<context source="yes">
\bTABLE
\bTR
\dorecurse{8}{\expanded{\bTD\recurselevel\eTD}}
\eTR
\eTABLE
</context>
Multi-dimensional tables offer another illustration:
<context source="yes">
\bTABLE
\dorecurse{8}{
\bTR
\dorecurse{5}{\bTD #1,##1 \eTD}
\eTR
}
\eTABLE
</context>
Alternatively, (mkiv only?)
<context source="yes">
\bTABLE
\dorecurse{8}{\bTR
\dorecurse{5}{\bTD \currentTABLErow,\currentTABLEcolumn \eTD}
\eTR}
\eTABLE
</context>
