Having been totally led astray by the enigmatic "Use of uninitialized value in string eq" warning, I am now boggled.

This snippet of code gives the warning "Use of uninitialized value in string eq" 

my %data = @_;
warn $data{'FLOATER'};
print $data{'FLOATER'}."<-----------";
if( $data{'FLOATER'} eq 'Y' ){

This is in a subroutine, hence the use of @_. The warn and print statements are for debugging this warning, and both show this hash key to hold the value "N". A defined($data{'FLOATER'}) returns true. What am I missing?

I have searched for similar problems with this error string, but it is so common that I haven't found anything useful. I have tried different combos of quotes around the hash key, and the constant 'Y'. Nothing seems to matter. I have also seen the same warning with similar code, but different values.
