Hi Alex,

 >>I never asked to anybody on the board this issue. <<

I understand.   But several of the board members are now obviously aware 
of your desire to have a GOTO instruction in the LinuxCNC
gcode language.

 >>I honestly don't know how to do it .

Ok..  I didn't know.   I just wanted to try and help you.
So you will need to convince someone else to alter the program and submit a 
patch for review.  Then it may or may not be
included in the official releases of LinuxCNC in the future.  However, if you 
have a patch, you can apply that to LinuxCNC yourself
and recompile the program and gain that functionality.  There are instructions 
on the LinuxCNC website on how to get and compile
the LinuxCNC source code.

>>Never in my mind to see a so strong reaction from a part of the people I
read .<<

Don't take it personally.

Some programmers have strong negative feelings about the GOTO instruction.
Some really horrendous code has been written with the help of the GOTO 
instruction.
Extensive use of the GOTO instruction is generally associated with bad 
programming practices.

>>Can you kindly explain me how to express an official request to the LCNC
board of developers. <<
Making an official request to the board may very well result in no changes 
unless they personally are interested in making
the changes.

Here is the official "How to contribute web page".

>>First of all I'm not so comfortable with the english writing to express my
self fully .<<

You do very well.

>>I tried during the thread to explain why the GOTO (or whatever
function/instruction can do the same thing) can be useful to produce clear
and well structured G code but maybe I failed .<<

I don't think that was an argument that you or anyone else could win on this 
list.

>>If a feature is transversal between different CNC manufacturers to be a
sort of "standard" why LCNC shudn't have it ?

Good question.

Regards,

Dave
