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);
^ remove the space
drawarrow A; drawarrow B; drawarrow C ; drawarrow D ; \stopMPcode
Unless I uncomment D it gives the above error.
Mysterious issue
