Definition of constants with CONST
Possibilities of defining constants:
Direct assignment of values
Internal interpreter information as constants
Assignment of names to the transfer variables of subprograms
Use the following internal information to define constants in the
CONST section.

Subprogram transfer values
The constant _pi is predefined to the value
3.1415926535989 and can be used directly in every NC
program.
