LinePrinter
The maximum
LPRINT
or
LUST
line is
255
characters (was
132).
Passwords
You can assign a password to a program when you
SAVE
it. This password will be
required for loading or running the program.
Line Feeds
You can include line feeds in the program text,
SAVE
the program in
ASCII
format,
and
LOAD
the program later (used to cause a Direct Statement error). Each line feed
in the file requires two bytes of diskette storage.
Take care not to create a line that will require more than
255
bytes for storage. This
maximum includes the line number digits and the space following the line number.
If the line contains embedded line feeds, allow two bytes for each line feed.
