ClOAD "PR03"
Loads the first program from the tape.
Searches the tape for the program named "PROT' and loads it.
Notes:
1. The computer cannot identify the stored contents as a program or a reserve. Therefore, if a mode is designated incorrectly,
the reserved contents may be transferred to the program area or the program to the reserve area, causing the computer to remain
inoperative. If this happens, reset the computer by pressing the RESET button on the back of the computer.
2. If the designated filename is not retrieved, the computer will continue to search for the filename even after the tape reaches the
end. In this case, stop the retrieval function by pressing the
~
key. This applies to MERGE, CHAIN, CLOAD? and INPUT#
commands to be described later.
3. If an error occurs during CLOAD or CHAIN command (to be described later) execution, the program stored in the computer
will be invalid.
