Data transfer: System memory into R parameter

The main group 3 is organized as follows:
@ 3 x y Three-digit @ code
Special function
0: Machine data
1: Setting data
2: Tool offsets
3: Zero offsets
4: Programmed setpoint values
5: External setpoint values (available soon)
6: Actual values
7: Program data
3: Main group 3
All @ commands in main group 3 have <Var> as first notation. This defines directly or via a
pointer an R parameter in which the contents of the addressed system cell are to be loaded.
Main group 3/subgroup 0: Transfer machine data in R parameter
@300 <Var> <Value 1>
The address of an NC machine data is defined in <Value 1>.
Address area: 0 to 4999.
Example:
@300 R50 K2240
@301 <Var> <Value 1>
The byte address of an NC machine data is defined in <Value 1>.
Address area: 5000 to 18240.
@302 <Var> <Value 1> <Value 2>
The byte address of an NC machine data bit is defined in <Value 1>.
Address area: 5000 to 18240. The bit address (0 to 7) is given in <Value 2>.
@303 <Var> <Value 1> <Value 2>
The cycle machine data values are read into parameter<Var>.
Where:
<Value 1> Channel No.
0: own channel
<Value 2> Word address
