11.2 Target code
11.2 Target code
The three-digit @ code is a target code with the following structure:
123
Last (third) digit for defining the special function.
Middle (second) digit for dividing the main groups into subgroups.
First digit for distinguishing the main groups.
@
Three-digit @ code
11.2.1 Main groups
The following functions are assigned to the eight groups of the @ code:
@0 . . General instructions for program structure
@1 . . Program branches
@2 . . Data transfer, general
@3 . . Data transfer, system memory in R parameters
@4 . . Data transfer, R parameters in system memory
@5 . . File handling, general (available soon)
@6 . . Mathematical and logic functions
@7 . . NC-specific functions
@f . . Part program handling
11.2.2 Operands behind the target code
The @ code requires additional information (operands) for its function.
These operands are defined by the following letters:
K . . . Constant
R . . . R parameter (register)
P . . . Pointer
The value defined by the constant K is fixed within the program and cannot be modified (direct
specification of value).
The value defined by the constant K is fixed within the program and can be modified (indirect
specification of value).
The pointer refers to a parameter containing the address of the parameter to whose contents
the function is to be applied (indirect specification of value).
