I did have to change the comments in my mapfile to be sure I had ## rather than just #. Otherwise errors and missed lines happened.
Thanks for the info.

Hi,
AFAIK you cannot create variable in the map file, but you can use the
cpp (the c preprocessor) to create macro substitution.
For example
#define HIGHWAY_COLOR 123 43 112
#define HIGHWAY_MAX_SCALE 1600
...
MAXSCALE HIGHWAY_MAX_SCALE
...
COLOR HIGHWAY_COLOR
...
then
cpp map_file_with_defines > generated_map_file
Bye
