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)
