Hi,

Where it it defined?

The language report says "CAP(x) character type type of x
    x is a Latin-1 letter: corresponding capital letter".

I can't see where it defines the result if x is not a Latin-1 letter.

Thankyou for the suggestion. I have several years experience of
writing professionally in assemblers for ICL and IBM mainframes,
and for PCs, although I have not done so for some years.

As Tei has pointed out, the particular method that Chris describes
is not very portable and not very international. However, the language
report does specify Latin-1, so it seems that the language definition
contains an implementation bias.
