Oops! From PoOps:
Proceeding from left to right, the elements of the second operand are
compared with the corresponding elements of the third operand and
optionally with zero.
"Corresponding element" is the problem.
If the second operand is <TAB><SP><TAB><SP><TAB><SP><TAB><SP>
and the third operand is <SP><TAB><SP><TAB><SP><TAB><SP><TAB>
I believe I'll never get the desired match. TRT seems to remain
the winner.
No. Remember, these are vector operations. ALL ELEMENTS of the third
operand are compared (in parallel i.e. simultaneously!) with the
elements of the second operand proceeding left to right.
This is not theory. We use this HEAVILY in production software that's
been in the field since September 2016 and it *CRUSHES* TRT!
Just try it rather than thinking you understand it from a
misinterpretation of PoOp.
