Indirect programming

Indirect programming enables programs to be used
universally. The extended address (index) is
substituted by a variable of suitable type.
All addresses can be configured, except for:
• N – block number
• G – G command
• L – subroutine
Indirect programming is not possible for any settable
addresses.
Example: X[1] is not permitted instead of X1.
