Re: Opposite of %CHECK?

[John Yeung <gallium.arsenide@xxxxxxxxx>]

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.
