Type of operation:
A Address
Identifier to which a value is assigned (e.g. OVR=10). There are also some addresses that
switch on or off a function without value assignment (e.g. CPLON and CPLOF).
C (A) AST cycle
Predefined NC program for automatic post optimization (tuning) with AST (= Automatic
Servo Tuning). Parameters are used to adapt to the specific optimization situation; these
parameters are transferred at the call.
C (M) Measuring cycle
Predefined NC program in which a specific, generally valid, measuring operation, such as
determining the inner diameter of a cylindrical workpiece, is programmed. Parameters are
used to adapt to the specific measurement situation; these parameters are transferred at the
call.
C (T) Technological cycle
Predefined NC program in which a specific, generally valid, machining operation, such as
tapping of a thread or milling a pocket, is programmed. The adaptation to a specific machine
situation is realized via parameters that are transferred to the cycle during the call.
F Predefined function (supplies a return value)
The call of the predefined function can be an operand in an expression.
G G command
The G commands are divided into G groups. Only one G command of a group can be
programmed in a block. A G command can be either modal (until it is canceled by another
command of the same group) or only effective for the block in which it is programmed (non-
modal).
K Keyword
Identifier that defines the syntax of a block. No value is assigned to a keyword, and no NC
function can be switched on/off with a keyword.
Examples: Control structures (IF, ELSE, ENDIF, WHEN, ...), program execution (GOTOB,
GOTO, RET ...)
O Operator
Operator for a mathematical, comparison or logical operation
P Predefined procedure (does not supply a return value)
PA Program attribute
Program attributes are at the end of the definition line of a subprogram:
PROC <program name>(...) <program attribute>
They determine the behavior during execution of the subprogram.

Effectiveness of the operation:
m Modal
s Non-modal
3)
Programmability in part program:
+ Programmable
- Not programmable
M Programmable only by the machine manufacturer
