Meanings of this code

Could someone please explain what the functional difference between these two blocks of code?

VAR X_POSITION = [X|A|X|1.3]
VAR Y_POSITION = [Y|A|Y|1.3]

VAR X_POSITION = [X|C|X|1.4]
VAR Y_POSITION = [Y|C|Y|1.4]

The A and the C, the 1.3 and the 1.4

Thank you in advance

from the Vectric post processor help file:

When output, A=Always | C= Only when Changed.

1.3 output will be to 3 decimal places, this would typically be
suitable for a control that requires metric output.

1.4 If you wished to output the values to
4 decimal places as would be more typical
for a controller operating in inches

hope this helps..

you may tell us also where the Code Postprocessor comes from
not only the Code itself

I'm not sure where I found the post, I was just stumbling around looking at different pp's and noticed the difference and was curious.
I didn't realize the information was in the help manual.

Thanks again
