The Gurobi documentation is at

Both don't define inf and infinity as allowable values for the
right hand side of a constraint. On the other hand they don't
explicitely exclude it.

Ah. I had seen Gurobi's version, but I interpreted it more as a first-pass introduction to the LP format, rather than a complete specification or grammar. CPlex's version seems a tad more thorough, but is still not complete by my understanding of a grammar.

In any event, I very much appreciate your code snippet. I don't yet have that internal understanding of the GLPK code base to whip it out so quickly. Is there any chance that will be included in the next GLPK release?
