>I'd appreciate (and I'm sure a whole bunch of lurkers would also appreciate) a piece of code that demonstrates the 'evaluate differently at run-time'.

I haven't read all of this thread and maybe I'm confused what the problem is. But this is my understanding of #DEFINE:

If you (in header file or methods, prgs, etc etc) have #DEFINE in your code, such as:

#DEFINE Now DATE()

And then use it like this:

REPLACE mytable.updated with Now

and

ldTomorrow = Now + 1

And then it being compiled, then compile just replace all the Now with DATE(), so it actually sees the code (before compiling!) as:

REPLACE mytable.updated with DATE()

and

ldTomorrow = DATE() + 1

#DEFINE doesn't "Evaluate" at compile-time nor run-time. There is no "DEFINE"'s in a compiled program. The code is just dublicated. Of cause "Evaulate" could be a play on words of what the compiler is doing.

HTH,
