I've a 5 axis mill with iTNC530 and want to be able to view from status monitoring software the value of a variable set in Q99.
In Fanuc I could DPRNT this out via RS232.

Is there an equivalent in Heidenhain world please?

Or. via tcnrmo/tnccmd on a local PC it is possible to view Machine Parameters and other bits of data in the control over Ethernet but I cannot find out if its possible to view a QXX variable.
does anyone know the syntax to do that?

Or can I create a Machine Parameter and use it as a variable that tnccmd will view, something like MP99 = Q99 and the MPGET 99 (assuming for the moment that there isn't a machine parameter 99 already existing)

Hopefully.
