This does not answer the question as stated in the subject line, but does
fit your use case: if you have a recent enough RPG, use the %UPPER built-in
function to see whether anything got converted to uppercase. E.g. if
%upper(myvar) <> myvar then myvar contains lowercase.

I'm looking for an easy way to determine whether a character string
contains at least one lowercase character.

I can see that %CHECK() will tell me if there's at least one character
in "base" that *doesn't* appear in "comparator," but is there an easy
way to determine if there's at least one character in "base" that *does*
appear in "comparator"?

Or do I have to do a %CHECK with a big, long "comparator" that contains
everything *but* lowercase letters?
