Hello,
You should change all of the "=" to ":=", as in
u := 1cm;
This instructs metapost to assign a value to the variable;
the standard form "u = 1cm" is a formula for metapost to solve.
It tries then to resolve u = 1cm; xmin = -2.6u; and xmax = 4u;
as a coupled set of equations. Sometimes you c

Hi,
See the following example:
\starttext
\startMPcode
u = 1cm;
xmin = -2.6u;
xmax = 4u;
drawarrow (xmin,0)--(xmax,0);
\stopMPcode
\stoptext
It can be compiled rightly. But when I add the 'label' line into it, see:
\starttext
\startMPcode
u = 1cm;

Is this a bug or it always need to use 'save' macro to hold these
local variable in metafun?
It is a side-effect of MkIV running your code through metapost
multiple times. But why it does that, I am not sure.
Best wishes,

Hi,
See the following example:

u = 1cm;
xmin = -2.6u;
xmax = 4u;
drawarrow (xmin,0)--(xmax,0);

u = 1cm;
xmin = -2.6u;
xmax = 4u;
drawarrow (xmin,0)--(x
