1.2
Function
In addition to the predefined variables, programmers can define and initialize their own
variables.
Local variables (LUD) are only valid in the program where they are defined.
Global variables (GUD) are valid in all programs.
Machine data are used to redefine the local user variables (LUD) defined in the main
program as program-global user variables (PUD).
