I'm having a spot of trouble with a script...

[(imagertr:$LOGNAME)$PWD]: unset study;export study
[(imagertr:$LOGNAME)$PWD]: echo $study

[(imagertr:$LOGNAME)$PWD]: echo $study|wc -C
       1
[(imagertr:$LOGNAME)$PWD]: echo ":$study:"
::
My intuition says that "wc" should report "0"
My intuition says that when my intuition is wrong I'm being an idiot 
about something
:-)
