The goal is to make the following string in metapost:
string s; where s must become "\MPcolor{Blue}".
and ultimately execute this at the right moment with: scantokens s;
The following makes s = "MPcolor{Blue}":
s := "MPcolor" & char oct"134" & char oct"173" & "Blue" & char oct"134" &
char oct"175";
But I seem unable to add a \ in front of it without expanding the string by
TeX. Thus it does not work to put:
s := char oct"134" & "MPcolor" & char oct"134" & char oct"173" & "Blue" &
char oct"134" & char oct"175";
Placing a \noexpand in front does not help.
How to?
