OK; that is not the problem.  I used tab_i with the same result.  Clearly 
arrays are better and more natural for this applicaion baut there is 
somwething wrong that needs fixing.  Back to mainstream debugging.....

The problem is rounding.  The value of itabndx is not 1 as you assune but
0.99999999999997868

The line thar convertts this to an integer does not round in table or 
tab_i

T¬h`e `equivalent code in array access rounds.

The questuon now is wheter we can y`just att rounding, or wll that break 
things of old.

Further to rounding in table opcodes; suse iwrap=2 to get rounding -- at 
least te code says that!  tab opcodes now round by default
