Variables and constants are lumped together under the term "DATA" (surprise!) This explains BASIC's use of statements such as DATA 4,5,7 which are the equivalent of constants, since they are fixed at write time. And obviously variables, once intiialized, are also data, which can change during the run. Procedures and functions are not data. Operators are not data. Literals are unnamed constants - so they may qualify as data, I dunno. Irv
