formula in text to add

Hi. I'm using AutoCAD 2008. I have a schematic drawing that looks like:

C01-N01

C01-N02

C01-N03

C01-N04

Sometimes the C# changes and sometimes the N# doesn't start with 1.

Can I put a formula in subsequent text to add 1 so if I change the first line from C01 to C02 all other text with C01 will change to C02?

I've been searching and coming up with no answers. Time to turn to the experts.

I have a few VBA & LISP routines I use depending on what I want the final result to be but I haven't found a way to do it directly. One of my routines puts an array of incrementing numbers down which is ideal for numbering terminal blocks. In another you can click a piece of text and the routine will add a value in a particular position. A further one concatenates two pieces of text and copies it to a third piece.

More often I just type it by hand. What I keep thinking of doing is a routine where you set the first piece of text and its "rules" and then just click where you want the text to appear. mmmm, maybe I should do it now. No, too busy. I am sure Lee will be along with something as soon as his exams are over.

AutoCAD's built in Find/Replace should be able to change all the C01s in C02s. Unless if I missed the question.

I would be inclined to agree with Fuccaro,

Unless we are missing something.

If not, maybe this will help you:
