Mid$ Syntax Mid$ ( Variable AS String , Start AS Integer [ , Length AS Integer ] ) = Expression Mid ( Variable AS String , Start AS Integer [ , Length AS Integer ] ) = Expression This syntax allows to modify the contents of a string variable. It is just syntactic sugar, i.e. the compiler internally replaces: Mid$(Variable, Start, Length) = Expression By the following code: Variable = Left$(Variable, Start - 1) & Expression & Mid$(Variable, Start + Length)
