Of course you can use reserved words like "pi" or "int"
with the "over" construction. For example, modify
"Example" so its output looks like the following, then
alpha over beta ~=~ pi over 2
#once neqn Ref | nroff >X1 &
#once neqn message Ref | nroff -T$term %s/tinyms -
The names are alpha, beta and pi.
I hope your trouble wasn't any more
