It looks massively convoluted to me !

Thanks, these work nicely.
I've made some wrong assumptions at the highest level.
That's why 'top-down' design is best.
If I use positioning the caret after the closing-'bracket'
AND selecting up to the closing-'bracket', AND the
closing-'bracket' is off screen then [apparently] the
caret-stepping, looses the beginning selection of the
block. It's what it LOOKS like to the user that matters.
I favour data/table-driven programming, where possible.
Then many types of nested-bracketed-text can be
handled, other than "IF <expn> THEN <stmt> END"
I'll start putting it to Edgar's wiki.
For those like me, who don't want their text to be
auto-reformatted, use short lines and '[[BR]]' as a
line-terminator for wiki.
Now I'm going to try to post & paste:
A problem is to quickly see the block-structure of source code[[BR]]
when the blocks/nested-statements extend over multiple screens.[[BR]]
