Commands
and
Statements
6-20
REM
The REM statement
is
used to insert commentary remarks into program text. Any
instruction line that begins with REM following its line number
is
passed over, and
program control passes to the next line. Within a remark, : (colon)
is
simply another
character, not a statement separator.

RENAME
The RENAME command changes the name
of
the specified file to the new filename.
Only the directory reference (accessed with the DIR command)
is
altered; if pro-
grams reference the old filename, a FILE
NOT FOUND error message will result.

filename"
TO
"new
filename"
RENUM
The RENUM command resequences line numbers in a program, whether they ap-
pear
at
the beginning
of
a line or as the object
of
a OOTO statement. You can
specify up to three optional arguments: the first
is
the new number
of
the first line to
be renumbered, the second
is
the old number
of
the first line to be renumbered, and
the third
is
the increment between lines.
If
you specify no arguments, the new
number
of
the first line to be renumbered
is
assumed to be
10,
all lines are
renumbered, and the increment
is
assumed to be
10.

RESTORE
The RESTORE statement resets the READ pointer to the first DATA statement
within program text. The DATA statements can then be reread. A line number can
be specified following
RESTORE; if included, data on the specified line will be read
next.
