If you define a subprogram within your NC program (within the same
file), it is designated with SUBPROGRAM, followed by the name of
the subprogram (max. 8 characters).

CONST code
In the CONST section of the program you define constants. You use
constants for the definition of:
„ a value

„ a V variable
You enter the value directly or you calculate it. If you use constants in
the calculation you must first define them.
The length of the constant name must not exceed 16 characters.
