Fundamentals of programming

11.1.1 Program names
Each program must have a program name. The program name must follow the conventions below:
● Use a maximum of 24 letters or 12 Chinese characters for a program name (the character length of the file extension
excluded)
● Separate the file extension only with a decimal point
● Enter the file extension ".SPF" if the current default program type is MPF (main program) and you desire to create a
subprogram
● Enter the file extension ".MPF" if the current default program type is SPF (subprogram) and you desire to create a main
program
● Do not enter the file extension if you desire to take the current default program type
● Avoid using special characters for program names.
