Flowmark is a text macro language influenced by TRAC T64, designed to be the base language for a possible typesetting toolset in the future.

The following is an example of the factorial function:
\def(Factorial,(\
\ifeq.int(<1>,0,\
0,\
(\ifeq.int(<1>,1,1,(\mult.int(<1>,\call(Factorial,\sub.int(<1>,1))))))\
)\
));
\init.macro(Factorial);
\print(\call(Factorial,5));
The following is an example of a solution to the Tower of Hanoi problem.
\def.free($,(\print((
))));
\def(Hanoi,\
(\ifeq.int(<1>,0,,\
(\ifeq.int(<1>,1,\
(\print(Move from to )$),\
(\call(Hanoi,\sub.int(<1>,1),,,)\
\print(Move from to )$\
\call(Hanoi,\sub.int(<1>,1),,,))\
))\
))\
);
\init.macro(Hanoi,,from,to,via);
\print(\call(Hanoi,3,A,C,B));
