2. Collating the Computer and Tape Contents
Now that the your program is saved on tape, you will no doubt want to see if it is really there. To do this is relatively simple;
use the CLOAD? command.
(1) Turn off the REMOTE switch to clear remote control functions.
(2) Rewind the tape to the place at which you started, again using the number counter.
(3) Turn on the REMOTE switch to set remote control functions.
(4) Depress the PLAY button.
(5) To collate the program with a filename type:
CLOAD
(SHIFT)
?
(SHIFT)
"PRO-1
(SHIFT) "
Press the
(ENTER)
key.
The computer compares the CSA VEd program with the one in its memory. If all went well, it will display the "prompt" and end
its check. If all did not go well, an error message will be displayed, usually ERROR 8. This tells you that the program on tape is
somehow different from the program in computer's memory. Erase that portion of tape and start again.
3. Transfer from Tape
(1) Turn off the REMOTE switch.
(2) Rewind the tape to the place at which you started, again using the number counter.
(3) Stop rewinding.
(4) Turn the REMOTE switch back ON.
(5) Press the PLAY button.
