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 :-)
