The RECORD command accepts variables for its parameters. It is
often convienent to place a RECORD command within a FOR ...
NEXT or DO loop. Also see DOPEN and OPEN.
REM
—Comments or remarks about the operation of a program line
REM message
The REMark statement is a note to whoever is reading a listing of the
program. REM may explain a section of the program, give informa
tion about the author, etc. REM statements do not affect the opera
tion of the program, except to add length to it (and therefore use
more memory). Nothing to the right of the keyword REM is inter
preted by the computer as an executable instruction. Therefore, no
other executable statement can follow a REM on the same line.
EXAMPLE:
10 NEXT X:REM This line increments loop index X.
RENAME
—Change the name of a file on disk
RENAME "old filename" TO "new filename" [,Ddrive
number] [<ON | ,>Udevice number]
This command is used to rename a file on a disk, from the old
filename to the new filename. The disk drive does not RENAME a file
if it is OPEN. The default drive is 0, default unit is 8.
EXAMPLES:
RENAME "TEST" TO "FINALTEST"
RENAME (AS) to (B$),D0,U9
Change the name of the
file "TEST" to "FINAL
TEST".
Change the filename
specified in A$ to the
filename specified in B$
on drive 0, device
number 9. Remember,
whenever a variable
name is used as a
filename, it must be
enclosed in parentheses.
