I meant a SINGLE constant. Imagine - you need to build query conditions in runtime and user typed all these characters. You make following:
MyConditions = MyConditions + ' AND [' + UserInput + ']'
...
SELECT ...
WHERE &MyConditions

Above will not work when UserInput contains all ', " and []. Need to use special string functions to split it apart as you mentioned. Why so complex? Why not just make it As I use now for SQL Server:
MyConditions = MyConditions + " AND '" + STRTRAN(UserInput,"'","''") + "'"
Above is MUCH more easy and I wery wondered why VFP don;t have such feature. :(

You can,

lcMyString = [a string with ', " and ] + " [] is possible in VFP"
