Re: undefined variable problem

Check out Catherine's reply again. I think you may have misunderstood
what the compiler means by "undefined". It doesn't mean "not allocated"
or "not declared" or "not associated". It means "used before set" -
i.e. no value has been assigned to a since it was created (by allocation
or whatever). It is an error to use the value of a variable if it has
never been given a value, and that is what the compiler is complaining
about.

Yep. I indeed misunderstood what the compiler was telling me.
It has been a while since i've compiled my code with NAGWare's
f95 and the -C=undefined option. Now that I'm compiling with
this setup, it seems that there are quite some places where I use
undefined variables... djeez, do i love this compiler switch! :-)

Thanks,
Bart
