!AWApr92/Goodies/All_At_C/TextFile

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Last time we looked at how to pass command line arguments to our program, and made it accept input and output file names.  We are now in a position to greatly extent this feature, and implement some more options, such as controlling the recognition of upper and lower case letters, the minimum word length, and the format of the output file, etc.  To do this we need a method of handling a variable number of command line arguments, supplied in any order.
