>m. is used to distinguish memory variables (m stands for memory) from the fields. It's not really needed, but in some cases when you have a field in a table named the same as a variable, you need to use m. to tell the program you meant memory variable and not a field (fields always have precedence).


oh wow i dont need anythin thing like () or "" i thought i would since its a variable and it added the () for me like ("status")
