The number of lines being sorted makes o difference.
The number of distinct sorts will - but at a single 'do' for each of
"several hundreds", you'll not even notice except (maybe) if you are
benchmarking it (around 5ms per 1000 'do's on an elderly MacBook Pro).

Okay. Thank you Ralph.
I was reluctant to use "do" for performance reasons. The sort could be
sorting a large number of lines - as many as several hundred sorts of
a thousand to ten thousand lines.
I could of course do timing trials, but does anyone from the
mothership (or anyone period) know if using "do" with a container sort
causes any appreciable performance hit? All the data is in a variable
(vs fields).

I found that you must us a "Do"(thank heaven for "Do"s) if you want
to make variable any LC token that colorizes like "stack", "the",
"field", "button", "put" or "ascending".
I don't think "Do" is a kludge is this case.

Subject: sort container parameters
I just discovered much to my dismay that you can not execute the
following:
put "ascending" into tDirection
soft lines of tContainer tDirection international
apparently neither the sort direction (ascending|descending) nor the
sort type (international|text|datetime|numeric|binary) can be variable!
That means if you want to parameterize a sort direction, you have to
do something like:
if tDirection is "ascending" then
sort lines of tContainer ascending international else
sort lines of tCOntainer descending international end if
I see this a a bug or perhaps a failure to fully robust impliment the
sort container command? Does any one else see this as a bug?
I suppose I could work around it with a "do" but that seems like a
cludge
do ("sort line of tContainer" && tDirection && tSortType)
Thoughts? Comments? Opinions? Am I expecting too much of LiveCode to
have sort direction and type actual parameters?
