I found the NISTIR 6012 PDF (The NIST DMIS Interpreter) on the
'net. Recognizing words, strings, numbers and operators is a good
baseline.

It looks line-based, so the lexer can rewind to a start-of-line
for easy processing. If words are unique, keeping some state will
enable highlighting of words based on their position in a statement.

A lexer can probably be cobbled together with the help of bits and
pieces from different lexers...
