—Concatenate two data files
CONCAT "file 2" TO "file 1"
[,Ddrive number][<ON | ,)Udevice]
The CONCAT command attaches file 2 to the end of file 1 and retains
the name of file 1. The device number defaults to 8 and the drive
number defaults to 0. Both files must be on the same disk.
EXAMPLE:
CONCAT "FILE B" TO "FILE A"
CONCAT (A$) TO (B$), D1, U9
FILE B is attached to FILE A,
and the combined file is
designated FILE A.
The file named by B$ becomes
a new file with the same name
with the file named by A$
attached to the end of B$—This
is performed on Unit 9, drive 1
(a dual disk drive).
Whenever a variable is used as a filename, as in the last example,
the filename variable must be within parentheses.
—Continue program execution
CONT
This command is used to restart a program that has been stopped
by either using the STOP key, a STOP statement, or an END state
ment. The program resumes execution where it left off. CONT will
not resume with the program if lines have been changed or added to
the program or if any editing of the program is performed on the
screen. If the program stopped due to an error; or if you have caused
an error before trying to restart the program, CONT will not work. The
error message in this case is CANT CONTINUE ERROR.
—Copy files from one drive to another in a dual disk drive, or within a
single drive
COPY [Ddrlvo number,]"source f ilename"TO"destinatlon
fllename"[,Ddrlve numbor][<ON | ,)Udevico]
This command copies files from one disk (the source file) to another
(the destination file) on a dual-disk drive. It can also create a copy of
a file on the same disk within a single drive, but the filename must be
different. When copying from one drive to another, the filename may
be the same.
