This is a little hairy - I have about 4000 labels with Stations and a weld number along a pipeline and the stations are all going to increase or decrease depending on new data being provided.
Here are a few random labels:
0+57 MLC-25
748+94 ATI-16
Only the stationing needs to be changed - so if they all increase by 6, it would be 0+63 MLC-25 or 749+00 ATI-16.
Is there a lisp out there that will do that? Assuming I need to remove the +, modify the number and place the + back in.
Thanks for any help!
