>Great, Ed. Thanks a lot. One little problem: [A-Z] could be also space, e.g.
>in mask: lcMask = "999999X-X999999X-X999999XX-XX999999X"
>X could be upper alpha or space.
Like this is difficult? Change [A-Z] to [A-Z ]
This is definitely a case of RTFM; you neeed to read the docs to see what all the capabilities are.
