Word structure and address

Functionality/structure
A word is a block element and mainly constitutes a control command. The word consists of
● address character: generally a letter
● numerical value: a sequence of digits which with certain addresses can be added by a
Figure 10-1
Several address characters
A word can also contain several address letters. In this case, however, the numerical value
must be assigned via the intermediate character "=".
Example: CR=5.23
Additionally, it is also possible to call G functions using a symbolic name (see also section
"Overview of instructions").
Example: SCALE ; Enable scaling factor
Extended address
With the addresses
the address is extended by 1 to 4 digits to obtain a higher number of addresses. In this case,
the value must be assigned using an equality sign "=" (see also section "List of instructions").
