The set-file BASIC program creates or updates the synonym-defining item called qfile in the master dictionary of the current account.
set-file {account.name{file.name}} {alternate.name}
This provides access to the specified file name in the specified account.name by using the file name, qfile, in place of the file name parameter during any file-handling commands.
If an alternate.name is supplied, then the MD is updated with that name (instead of qfile).
Each time set-file is invoked, it overwrites the previous Q-pointer.
The same functionality can be achieved using path names.
