Hi, The following sample code is working well in the \startMPpage ~ \stopMPpage, but is not working in the \startMPcode ~ \stopMPcode.
The error message is \textfont0 is undefined (character 63) l.6 \setstrut\strut $A$ If I remove “$” from the code, it is also working in \startMPcode ~ \stopMPcode. Is there anything which I have to set for \startMPcode? Best regards, Dalyoung %%%%%%%% \startMPcode{doublefun} %\startMPpage numeric count, temp[], tt, minus, u; u := 1cm; path p,q,r; pair A,B,C,D; string varName, ss, pos[]; p := unitsquare xyscaled (8u,3.5u); draw p; pos[0] := "bot"; pos[1] := "rt"; pos[2] := "top"; pos[3] := "lft"; varName := "yxwz"; count := 0; pickup pencircle scaled 5pt; for i = 0 upto 3: drawdot (point i of p); draw lmt_text[ text = "$" & char(65+i) & "$", anchor = pos[i], offset = 2pt, position = point i of p, ]; endfor; %\stopMPpage \stopMPcode
