RUN "filename" loads the program from
disk into memory and runs it. RUN
deletes the current contents of memory
and
closes all files before loading
the program. If the R option is
included, however, all open data files
are kept open.
Loads the program from disk into
memory but does not delete the current
contents of memory. The program line
numbers on disk are merged with the
line numbers in memory. If two lines
have the same number, only the line
from the disk program is saved. After
a MERGE command, the "merged" program
resides in memory, and BASIC returns
to command level.
Deletes the file from the disk.
"filename" may be a program file, or a
sequential or random access data file.
To change the name of a disk file,
execute the NAME statement, NAME
"oldfile" AS "newfile". NAME may be
used with program files, random files,
or sequential files.
If you wish to save a program in an encoded binary format,
use the "Protect" option with the SAVE command. For
example:
SAVE "MYPROG",P
A program saved this way cannot be listed or edited.
