Not really a difference in crystal syntax (
as far as I know).
I tend to use singles because it is a SQL habit.
A caveat...
In crystal you may need to alternate use of these sometimes in different functions like instr()
Say you want to search a field for Pat's Place.
You would need to use the double quotes because the value has a single in it: instr(field,"Pat's Place")
Conversely search for The title is "Travel on a Dollar a Day"
You would need to use single quotes because your value is using the doubles: instr(field,'The title is "Travel on a Dollar a Day"')
