What I miss:

Boolean algebra: XOR

Inline Assembly: I don't expect it

Character level file manipulation: Instead of Line level

Variable value substitution: Instead of $a="blah", $b=chr($a), $c=$a AND $b, $d=asc($c), $e=val($c) I would like to just $b=val(asc($a AND chr($a))).

.EXE compiler or at least some way of putting the .KIX file into the KIX32.EXE file and creating USERDEFINED.EXE that cannot be dis-assembled.

Otherwise KIX is great, good work Ruud!
