Command Reference
Prog
Function: This command specifi es execution of another program as a subroutine. In the
RUN
• MAT mode, this command executes a new program.
Syntax: Prog ”fi le name”
Example: Prog ”ABC”
Description:
• Even when this command is located inside of a loop, its execution immediately breaks the
loop and launches the subroutine.
• This command can be used as many times as necessary inside of a main routine to call up
independent subroutines to perform specifi c tasks.
• A subroutine can be used in multiple locations in the same main routine, or it can be called
up by any number of main routines.

• Calling up a subroutine causes it to be executed from the beginning. After execution of
the subroutine is complete, execution returns to the main routine, continuing from the
statement following the Prog command.
• A Goto~Lbl command inside of a subroutine is valid inside of that subroutine only. It cannot
be used to jump to a label outside of the subroutine.
• If a subroutine with the fi le name specifi ed by the Prog command does not exist, an error
occurs.
• In the RUN • MAT mode, inputting the Prog command and pressing w launches the
program specifi ed by the command.
