Parameter programming

Parameters are used in a program to represent the numeric value of an address.
They are assigned values within the program, and can thus be used to adapt a program to
several similar applications (e.g. different feedrates, different spindle speeds for various
materials, different operating cycles). A parameter comprises address R and a number with up
to 4 digits.
