SUB is a compiled Clipper PRG program. It is 'freeware'. No fee is expected or
will be accepted. It's purpose is to go through RoboComm's NEW40.DBF (the
database that keeps track of new files on the BBS's you call).  It allows you
to change the file extension of the files in the Available Files list.  It's
syntax is simple, but VERY important.  It does not contain protection against
errors like typing NO parameters on the command line.

           The correct syntax is SUB <ext to replace> <replacement>

As an example, If you wanted to change all filenames with ARJ extensions to
filenames with ZIP extensions, the command would be:

                                SUB arj zip

The syntax is not case sensitive and no '/' are required.  A word of caution.
If you were to run the program leaving out the replacement extension like so:

                                SUB arj

all the files with ARJ extensions would end up with exactly what you told the
program to do, leave them with no extension at all.  I realize that with more
effort I could have put in some error checking to prevent this.  But, hey,
they're free and I didn't fell like making a project out of it.   Not to
worry, however.  For instance, if you ran SUB with no parameters, it would
turn all your filenames into FILE. with NO extension.  The same thing would
happen if you ran SUB with one parameter, the one to look for, but not the one
to change it to.  All the filenames that had the extension you listed would
have there extension removed.  BUT, simply run SUB again like this:

                                  SUB "" ZIP

and all the filenames with NO extension would end up with a ZIP extension.  So
if you accidentally run SUB on your filelist and put in no extension, or only
one, just run it again like above and it will interpret the "" as meaning no
extension and turn it into one with a ZIP extension.


SUB can reside anywhere, but you must be in the directory where you keep your
RoboComm files when you invoke it. The source code has been included for any
Clipper users that wish to play with it.
