4-3 User Variables
These variables can be shared by the same subprograms. They are 64-bit floating point arrays inde-
pendent in each subprogram. The user can use from L0 to L255, but cannot use L256 and subsequent
variables.
These variables can be shared by the same CNC coordinate systems. They are 64-bit floating point
arrays independent in each CNC coordinate system. The user can use from Q0 to Q4095, but cannot
use Q4096 and subsequent variables.
They are the sole 64-bit floating point arrays that can be shared inside the Controller. The user can use
from P0 to P32767, but cannot use P32768 and subsequent variables.
Indirection of variables that are used for parameters is available. It must be written in the form of Vari-
able prefix [Variable name].
The indirection cannot be used in the program code.
