Ctrl Command set_offset
Function defines an offset for
all subsequent coordinate transformations (see "Coordinate
Transformations", page 161).
Call set_offset( HeadNo, XOffset, YOffset, at_once )
Parameters HeadNo See set_offset_xyz.
XOffset,
YOffset
See set_offset_xyz.
at_once See set_offset_xyz.
Comments • See "Coordinate Transformations", page 161.
• The command functions similarly to set_offset_xyz , but leaves

5 unchanged primary functionality (offset definition), however:
• The parameters
HeadNo and at_once are new.
• Extended offset value range.

4) and the RTC
®
5
multiplies the specified offset values by 16 (the permissible range of values is
correspondingly reduced to [–32768 … 32767]).
