I don't know which way this should be fixed, but there is a mismatch:

data/TWiki/IfStatement.txt, line 31:

| <nop>=, !<nop>= | String comparison |

=lib/TWiki/If.pm, lines 126-134

$defOps{'!='} =
  { name => '!=',
    prec => 4,
    type => 1,
    exec => sub {
        my( $twiki, $a, $b ) = @_;
        return $a->evaluate($twiki) != $b->evaluate($twiki);

For string comparison, the third line from the bottom must read

        return $a->evaluate($twiki) ne $b->evaluate($twiki);

Workaround is to just say not(string1 = string2) instead instead of string1 != string2 if string comparison is needed.

Thanks Harald, it was meant to be string comp. SVN 6953 CC

Summary %IF docs say != is string, but implementation in If.pm treats as numeric
