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.
