Thanks, Alex... that's something I do when I need to, but it seems like more
of a workaround to me, which is why I'd rather have some kind of global
setting I could turn on when I needed it.
In some ways it's like like "the wholematches"... I don't believe we had
that in HyperCard, so if you were trying to see if a "whole" something
matched, you had to do slap the delimiters in front of and after everything,
like:
-- imagine field 1 has a CR-delimited list of different kinds of fruit
if offset((cr & pears & cr),(cr & tFruit & cr)) <> 0 then...
It's so much easier to say:
set the wholeMatches to true
if lineOffset("pear",tFruit) <> 0 then...
Maybe we should call it the "wholeChunks" ?
set the wholeChunks to true
put item -1 of "Ken,Ray,"
==> returns ""
??
