Thanks Yes, you first use a color for all edges (with the "linecolor" option, or the default color if you give no option) and then you can change individual edges with setTreeEdge. There are two examples on page 105 of the manual: setTreeEdge(Obj(t))(1)(linestyle)("dashed evenly"); setTreeEdge(treepos(Obj(t))(2))(1)(linestyle)("dashed evenly"); You can write setTreeEdge(Obj(t))(2)(linecolor)(red); setTreeEdge(Obj(t))(3)(linecolor)((1,1,0)); (these examples assumes that `t' is a numeric, as returned by T_, or _T; if you use newTree, you can just put the name of the object, and `Obj' should not be used) The first argument is an object, the second is an edge number, the third is an attribute, the fourth is the value of the attribute.

Hi there! In C there are so-called global static variables. These can be accessed by all functions inside the same source file, but are invisible to functions from other source files. Is there something similar in MetaPost? Or any workaround? I have a set of macros which share some information stored in global variables and I want to avoid conflicts with other macros.
