VFP offers the option of encapsulating strings in three ways - using single quotes - ' text text text ', double quotes - " text text text " or matched pairs of square brackets - [ text text text ]

The reason you'd choose one over the other is ease of use - if you wanted to place the phrase Ed's new book "How to confuse FoxPro" in a single string, and you didn't have the option of using square braces, you'd have to split up the string. You can do:

cMyString = [Ed's new book "How to confuse FoxPro"]

or

cMyString = "Ed's new book " + '"How to confuse FoxPro"'

to avoid having the parser misinterpret the string. It's a matter of flexibility, and has been a standard for Fox and other dBASE-derived languages for as long as I can remember.
