Hi to all,
I need some help with coding (I am not "code" man at all).
Somehow I manage to make work 3 diferent coordinate systems as desired, but, it is possible to make popup note with yes/no function?
here is basic code:

G55
G10 L2 P#<_coordsys> X0 Y91
M73 ;store state, auto restore
G17 G90 G91.1 G90.2 G08 G15 G94
M50P0 ;disable speed override
M55P0 ;disable trans
M56P0 ;disable warp
M57P0 ;disable swap
M10P1 ;motor enable
M11P1 ;limits/probe enable
(msg,Spindle to work pozition) //here would like to have choice yes/no
G00 X0 Y0
