Reading workingoffset values

[rui.costa]

Anyone knows if there is any way to automatically read a workingoffset and set a new one dependant of the first.
For example, I would like to automatically set the G59 X and Y as double of the G54 X and Y and keep the same Z in both G54 and G59, measuring only the G54 workingoffset.
I know that I can write to the G59 using
G90 G10 L2 P6 Xvalue Yvalue Yvalue
but I don't know if it's possible to read the information in a similar way.
I would like to do this on a Fanuc serie 310is-A5.

I think that other possible way is to make a custom Macro but I also don't know how.

Thank you all;

I never use G10 I just directly read/write to the variables.

On every machine I have seen the work offsets are at these variables and can be read and written. There may be some machines that are different but this seems to be one of the more widely used standards.
Not all machines use the Ext. offset or us them in the same way.

      Axis 1  Axis 2  Axis 3  Axis 4
Ext.  #5201   #5202   #5203   #5204
G54   #5221   #5222   #5223   #5224
G55   #5241   #5242   #5243   #5244
G56   #5261   #5262   #5263   #5264
G57   #5281   #5282   #5283   #5284
G58   #5301   #5302   #5303   #5304
G59   #5321   #5322   #5323   #5324

So
#5321 = [#5301 + 10.000]
Would set G59 X to G58 X plus 10 inches.

The extended offsets are a little less standard but they should be in the programming manual.

Also if you run out of variables in the #100 and #500 locations you can use the extra unused work offsets in your macros, same for tool offset varables.

This will help me a lot.
Now I just have to find how to put this in my NC code to run automatically and in the right way.

Thank you for your reply.

Try this

#5323=#5223(Z G59=G54)

Thank you both for your reply,

I already tested writing directly to the variables and it worked as I expected.
