Adding a linefeed to a gcode line

F-engrave allows the user to add a one line header. I want to have two pieces of gcode added:
G64 P0.001 and G4 P3
The three second delay is the ramp up time on my spindle.

Including both on the one line allowed results in an Axis error, it says I can't have multiple P words on the same line.
I tried inserting /n (and \n) in between; Axis complains about the slash.

Is there some other way to get Axis to interpret a single line of gcode as two lines, or to allow two P words?

Thanks!

Does the pipe character create a new line?

Nice idea, but it still says "bad character"

It works for me in master branch on the axis_mm sim using f-engrave 1.75
 

Weird. I tried it as you wrote, with just the G64/G4 on one line (other commands removed). I still get the error. I'm using Axis 2.8.4-76-g6082f1df7.

Aciera, I will try the subroutine and report back when I get a chance.
