The simplest solution is to start a counter, append it to your
base table name and simply use OnError to trap the error
generated when you try to open a table that doesn't exist.
A much more elegant (and general purpose) solution is to use the
GetFilenames() function in the "File, Director, Drive, Path"
section of the MapBasic Resources Center at
http://www.paris-pc-gis.com/mb_r/mbr_start.htm. This retrieves a
list of file names based on a standard DOS/Windows filespec
pattern. Source code is included as well.
