Echo calculated values ??

Is there a way for LInux cnc to echo a calculated value? Below is a snippit of code, I would like to echo the values of 'g' and 'g2' depending on changing 'd1' and 'd2';
Thank you, Dan

#<_dia> = 14.6875       ; this aligns with a 3/16 thick rolled band
#<_radius> = [#<_dia>/2]
#<_d1> = 3.02           ; This parametr sets the total length (currently 4 inches)
#<_d2> = 5.52           ; This parameter aligns the top of the arc with width
#<_theta1> = [asin[#<_d1>/#<_radius>]]
#<_theta2> = [asin[#<_d2>/#<_radius>]]
#<_g> = [#<_radius> - [cos[#<_theta1>] * #<_radius>]]   ; offset to start of part
#<_g2> = [#<_radius> - [cos[#<_theta2>] * #<_radius>]]  ; offset to end of part

 

from gcode you could use debug(18) or print(19)

linuxcnc.org/docs/2.8/html/gcode/overview.html#gcode:debug

I tried the following however it did print anything.

#<_g1> = [#<_radius> - [cos[#<_theta1>] * #<_radius>]] ; offset to start of part
#<_g2> = [#<_radius> - [cos[#<_theta2>] * #<_radius>]] ; offset to end of part

o1 ; Main program 1
(print,g1 = #<_g1>)
(print,g2 = #<_g2>)

For print to work you need to stat LinuxCNC from a terminal, then the result will be printed to the terminal. debug will make it appear in a popup message in the Axis GUI.
this worked for me:

Yes. That worked. Thank you. Dan
