One of the most common programs I use is this simple engraving program for Fadals. It uses the Fadal subroutine L9201 for engraving. I use it to engrave X,Y and Z information of fixtures or soft jaws along with customer, part number, or other relevant information.
I like to use an 1/8 “ spot drill. I eyeball my X0 and Y0 on the jaws or the fixture for the bottom left location of the first letter to be engraved.
You can see here I am using Tool 16 and the offset is E21.

N8 is the block that has the subroutine magic.
R1+ controls the font. 0=a standard gothic font
1=a stencil type Gothic font
2=a standard serialization font
3=serialization stencil font
R2+ is the height of your characters. The maximum is 2.5”
R3+ is the angle of the engraving.
R0+ is the clearance plane in between characters
There is also a R4+ value for incremental serialization of parts, but I’ll keep it simple here.
In N8 you can see at the end (PART# . This is where the characters to be engraved are entered. For example, to have part number 1234 engraved, N8 would look like this:
N8L9201R1+0R2+0.2R3+0Z-0.005F25.R+0.25(PART NUMBER 1234
Anything after the “(“ is what will be engraved.
N8L9201R1+0R2+0.2R3+0Z-0.005F25.R+0.25(I WAS HERE was my favorite to upset the foreman at a couple shops.
