Re: Clueless questions 3, 4 & 5 + HP LaserJet Thots

Norman,

3) These two are NOT the same:

   move '' to $var
   move ' ' to $var

4) Select expressions (column names) and the FROM keyword in a select
   must not be indented.  SQR commands inside a begin-select must be
   indented.

5) These two statements are functionally equivalent, but the first
   is faster than the second:

   move 'FOO' to $bar
   let $bar = 'FOO'
