depending on system you are you can do this via a Mcode
or using a INI Var
You can output the value of a parameter from G-code to a motion.analog-out HAL pin, and show that in the PyVCP.

I am making an engraving system and the idea is to see the serial number before executing the program (the serial number is stored in a variable)

as the serial number is to be engraved
you shoudt see it on the screen as gcode

yes, but the surface to be engraved is irregular and it is difficult to see it from gcode

You would need to send your G-code variable #20 out to HAL using M68
linuxcnc.org/docs/2.7/html/gcode/m-code.html#mcode:m68
Then connect motion.analog-out-00 to the PyVCP input pin.
(G-code can (unreliably) read HAL values, but can't directly write to them.)

but I have to send the values BEFORE executing the gcode, some method to read a variable and send the value to pyvcp without gcode ??

Maybe something like this would be better achieved using a filter script that reads your variable's value as the G-code is loaded and sets your pyvcp value then.

How does #20 have any meaning before the G-code is executing?

# 20 is the variable that stores the next number to write. I want to pass that value to pyvcp to visualize it before running the program.
