Command Reference
Prog
Function: This command specifies execution of another program as a subroutine. In the
RUN
•
MAT Mode, this command executes a new program.
Syntax: Prog ”file 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 specific 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 state-
ment 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 file name specified 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 specified by the command.
