But Bram tells me that some assembler files also use that same extension. What is a reliable way to distinguish the two?
I do not know how reliable it is, but searching for the Maxima assignment operator (I assume that is what := is.) looks like a possibility.
The usual assignment operator is ':'. ':=' is used to define functions. -- François Pinard http://pinard.progiciels-bpi.ca
