1.1 The Part Program
The Part Program is a set of instructions that can be interpreted by the control system in order to
control the operation of the machine.
The Part Program consists of blocks which, in turn, comprise words.
Word: Address and Data
Each word is made up of two parts - an address and a data. The address has one or more
characters, the data is a numerical value (an integer or decimal value). Some addresses may be given
a sign or operator I.
Address Chain:
Address Meaning Value limits

functions
