When I try using the variable listed in the reference document, most of them so not seem to work.

When I add this code to the Init Tool Change section
:T:<N><TOOL_COMMENT><EOL>
:T:<TOOL_DIAMETER><EOL>
:T:<TOOL_DESCRIPTION><EOL>

The output generated is
(M4.0 X 0.7 TAP)
<TOOL_DIAMETER>
<TOOL_DESCRIPTION>

Only the TOOL_COMMENT seems to work. Do you have to add additional code toe the LIB files to activate these variables?

Is there a variable I can use to extract the current Setup name and Operation name?
