That's a strange one. I can't replicate it with what you have provided. Are you sure you aren't using CHANGE as a variable or something somewhere else in your sketch?

Update:

I can get that exact same error by adding:

int CHANGE = 3;

in my sketch. That of course would convert to:

int 2 = 3;

The full error (in the Output tab of UECIDE) is:

I noticed that one of my interrupt lines had a point instead of a comma. making it

attachInterrupt(3, reedHigh2Int. CHANGE);

Fixed that and now it compiles..

Sorry for wasting your time.

D'oh... easily done. I have done it myself before now...
