Hi Bob,
You could also use regular expressions.
put LTrim(RTrim(" The cat sat under the mat " )) into tResult
function LTrim pText
get matchtext(pText, "(^[ \t]*(.*))", tFull, tPart)
replace tFull with tPart in pText;
return pText
end function
function RTrim pText
get matchtext(pText, "((.*)[ \t]*$)", tFull, tPart)
replace tFull with tPart in pText;
return pText
end function
(^ means start of word, $ means end of word; . means any
character; .* means any number (0 to many) of any character; [ \t]
means either space or tab (I added tab in case you want to remove
initial tabs as well).

Sometimes inexperienced Rev programmers have to ask questions that
make them want to crawl under the table in shame because probably
the answer is idiotically simple. Here is such a question.
If I have a string, say:-
" The cat sat under the mat "
- and I want to trim off the leading and following blanks to give:-
"The cat sat on the mat"
put word 1 to -1 of myVar into mySecondVar
Trimming only one end is slightly harder - in fact, the best way I
can think of is surprisingly complex
put char 1 to -2 of (word 1 to -1 of (t & "=")) -- could have
been any non-space character
put char 2 to -1 of (word 1 to -1 of ("=" & t)) -- could have
been any non-space character
Hopefully someone else will come up with an easier way, and I will
slap my head in annoyance :-)
