Anyway, = is both the assignment operator and the test for equality in Informix 4GL. But it seems to have obtained undocumented support for == somewhere along the way. Following the advice in the (fairly old) manual I skimmed through once, you should use = for both i = 20 and IF i = 20 THEN no need for the brackets in a simple expression like that. You've been writing too much c lately. And, Rajesh, what are these damn things?
