Okay. Thanks a bunch. I'm beginning to understand, but having messed with
wimpy interpreted DOS/Doze languages (QBASIC, VisBasic, and a neat one
called Euphoria) using pointers to access strings seems weird. Anyway,
what is the difference between a 'char **' and a 'char *'? I pretty much
understand everything else, but this eludes me.
