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 > !

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 > <to be read again> metapost log > : 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.
