Re: [WWdevel] Problem with num_cmp and strings

[Michael G. <ga...@ma...>]

Thanks very much John.  That was the problem.
I was pretty sure it was a flag set somewhere.
I'm not sure why the old macros couldn't handle this, but
I'm not going to worry too much about it.  Things seem
to be working well now.

Take care,

Mike
