UUencodes a file in PETSCII. (See 3.3.7.10, UUencode in PET)

5.4 Multiple file scratch

This option brings up the file selection screen and allows you to select
files to be scratched. Before bringing up a menu of files, Novaterm
prompts you for a pattern match. This allows you to enter
Commodore DOS wildcards to bring up only certain files. For
example, if you entered per*, only file names beginning with the
letters per are shown. Pressing RETURN here without an entry brings
up all files.

The file selection menu brings up the first 21 files on the disk and
displays them in the left-hand column. To select files, move the menu
bar to the file you want and press RETURN or F3. This puts the file
name in the right-hand column. Repeat this until you have selected all
of the files you want. To call up the next 21 files from the directory,
press F5. If you select a file you don't want, move the menu bar to
the file name in the right-hand column and press F4 to remove it.
Once you are finished, press F7 to start erasing the files you have
selected.

With the menu bar in the right-hand column, you may edit or add file
names by typing them in directly rather than paging through the
directory list. Move the menu bar to the file name you wish to edit,
and press RETURN. You may then re-type the file name. If you move
the menu bar to the blank line below the last file name and press
RETURN, you may type in a new file name.
