\recursedepth
Syntax
\recursedepth |
Description
The nesting depth in the case of nested \dorecurse, \dostepwiserecurse, and \doloop.
Example
\dorecurse{2}{ \recursedepth.\recurselevel:\crlf ---\dorecurse{3} {\recursedepth.\recurselevel\ } \crlf ---\doloop {\recursedepth.\recurselevel\ \ifnum \recurselevel=2 \exitloop \fi} \crlf }
