What bites is not your -tabplot- syntax, or so I imagine, but what it implies. The way that -separate()- works is that a separate call to -twoway rbar- is set up for each distinct colour and each of those is associated with several options. Clearly I didn't try to see what the limit really was and my implication in the help that you can have up to 20 distinct colours is unduly optimistic. My guess is that what fails is the final call to -twoway-: in essence -tabplot- is just a busy helper setting up the stage before the drama is enacted by -twoway-, but the -twoway- syntax implied by -tabplot- can be too much for -twoway- to handle.
