I'd say using TEMPs can speed things up in some cases because like Blue said=
 
they remain more constant and do not have to be reinitialized a hundred
times 
or whatever during execution.  When you are doing anything like counting, 
sorting, or anything like that I'd go with the DEFINE since it gets
redefined 
as data is manipulated.  Sometimes using TEMP in place of DEFINE works but
the 
data may not be what you expect.  Use caution.

I recently attended the Advanced Powerhouse Level 1 class.  I was taught
that it was better to use TEMP items than DEFINED items because DEFINED
items are only evaluated when you display the field or press enter at
the field.  However, the QDESIGN manual states that DEFINED items are
evaluated everytime they are referenced (which was my understanding
until I took the class).

Can anyone explain when to use a DEFINED item versus a TEMP item in
QDESIGN?  Do the same rules apply to QUIZ and QTP?

I generally use DEFINED items when the value of the variable does not
change based on different input conditions.  I use TEMP items when the
value of the variable changes based on different input conditions.

Thanks.
