Description
Calling frame
By specifying the system variable $P_UIFRNUM you can access the current zero offset set
with $P_UIFR or G54, G55, ...
($P_UIFRNUM contains the number of the currently set frame).
All other stored settable $P_UIFR frames are called up by specifying the appropriate number
$P_UIFR[n].
For predefined frame variables and user-defined frames, specify the name, e.g.,
$P_IFRAME.
Calling data
The axis name and the frame component of the value you want to access or modify are
written in square brackets, e.g., [X, RT] or [Z, MI].
