Word structure and address

Functionality/structure
A word is a block element and mainly constitutes a control command. The word consists of
S address character: generally a letter
S and a numerical value: a sequence of digits which with certain addresses can be added
by a sign put in front of the address, and a decimal point.
A positive sign (+) can be omitted.
Explanation:
Fig. 8-1
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
"List of instructions").
Example: SCALE
Extended address
With the addresses
the address is extended by 1 to 4 figures to obtain a greater number of addresses. In this
case, the value must be assigned using an equality sign "=" (see also Section "List of in-
structions").
Examples: R10=6.234 H5=12.1 I1=32.67
