MULTI COPY

This program will copy multiple files to a specified area. I
hope that this shit works too.

This program cannot copy files to a single file nor can it be
expected to know the difference between a file and a directory;

Therefore you must append a back-slash if copying
into a directory.

Example: To Copy COMMAND.COM into C:\tp7\code\work

You'd use MCOPY COMMAND.COM C:\tp7\code\work\
