CUSTOM FUNCTION: Supertrim ( text )
© Written by Debi Fuchs of Aptworks Consulting, (but please use freely!)

Speedily (and with no recursion) remove leading and trailing white space (including spacing, tabs returns, and line feeds) from a text string.

NOTE: Similar to TrimAll, except that it also removes tabs and returns and line feeds (in addition to spaces), and it does not touch any spacing WITHIN the string.

Supertrim(" John Smith¶") // --> "John Smith"

I've never written a custom function, so please forgive any oversights in this comment.

If I drop the space removal from the Substitute function, and add the char(160) how is Supertrim faster or different from

Trimall(Substitute( text; [ " "; "" ]; [char(160); "" ]; [ " "; "" ]; [ "¶"; "" ]; [ char(10); "" ] )) ?

Gary, the Supertrim removes leading and trailing whitespace characters, touching nothing within the middle of the text, e.g. "ban" & Supertrim(" ¶anas¶sour cherries¶pe ¶") & "ears" = "bananas¶sour cherries¶pears".
