G500 Selection of machine coordinate system (base coordinate system)/modal disabling of programmed displacements

The machine coordinate system is selected (modally). In other words, all absolutely programmed coordinates (e.g. X, Y, Z, I, J, K) relate only to the machine coordinate system. In the SRL program, the machine coordinate system is called the base coordinate system.

Difference from the standard: This command is additionally introduced to modally select the machine coordinate system.
