I'd like to see a way of doing a Regular Expression match on a variable
in the If structure. E.g. in my current install project, I'd like to
make sure the user selects the root directory of a drive as the
installation directory. I'd love to be able to do something like

If %_SB_INSTALL_DIR% Matches "^[a-zA-z]:\?$" Then

This would evaluate as true only if %_SB_INSTALL_DIR% contained only a
single character and a colon, followed by an optional backslash. Doing
this match without regular expressions requires much more complicated
logical expressions.

If you do this, please, please, PLEASE provide a better Regex
implementation than the lousy one Softvelocity provides for Clarion's
Match function (though I'll admit that that would be sufficient for the
example regex above). You might want to look at PCRE
(http://www.pcre.org/), which is BSD licensed, so it can be incorporated
into proprietary software.
