The following code gives an error, my goal is to draw 4 different arrows but only three functions successfully.
The error log shows
metapost > initializing number mode 'scaled'
metapost log >
metapost log > loading metafun, including
plain.mp version 1.004 for metafun iv and xl
metapost log >
metapost log > >> unknown path D
metapost log > ! Isolated expression.

metapost log > <*> ... :=(12cm, -1cm)--(11cm, -1cm); path D ; D :
metapost log > =(4cm, -1cm)--(3cm, -1cm)...
metapost log >
And the code is as follows
\startMPcode
path A ; A :=(0cm, -1cm)--(1cm, -1cm);
path B ; B :=(13.5cm, -1cm)--(14.5cm, -1cm);
path C ; C :=(12cm, -1cm)--(11cm, -1cm);
path D ; D : =(4cm, -1cm)--(3cm, -1cm);
drawarrow A; drawarrow B; drawarrow C ; drawarrow D ;
\stopMPcode
Unless I uncomment D it gives the above error.
