Sequence numbers in a CNC program Marked as Unimportant

[tteboe]

Thank you. Hopefully I will give a go yet today.
I was not even close to what you have illustrated.

See the Define Unimportant Text in Beyond Compare article on our website.

When you follow the instructions at the above link, select Basic, then check Regular Expression.
Use the expression: ^;?N\d+

Explanation of the regular expression:
^ - beginning of a line
? - match on 0 or 1 of the preceding character
\d - any decimal character
+ - one or more of the preceding character

See the "Regular Expression Reference" topic in Beyond Compare's help file for more on regular expressions.

I'd like to mark sequence numbers (N1... or ;N1...) as unimportant when comparing CNC output text.
I'd like to believe someone has either done this or something similar.
Items begining with "N" or ";N" are sequence numbers and will always have a white space after.
How do you go about telling BC to ignore N1 to infinity?

Below is an example output:
N7300 G505
N7310 G0 X0.0 Y.13893 Z442.21502 S2500 D1 M3 M52 M106
N7320 F300.
N7330 Z2.38882 D1 M07
N7340 CYCLE81(442.215,-0.111,2.5,-153.891,,0,0,0,12)
;End of Path
N7350 TRANS X0 Y0 Z0
N7360 TRAFOOF
N7370 SUPA G0 Z750. D0
;N7380 SUPA G0 X0.0 Y500. A0.0 B0.0 D1
N7390 CYCLE832(0,0,1)
N7400 M5

Thanks for taking time to look at this.
