Example:
Objective:
Insert a NULL character into a string, and then reconstitute the string.
Given:
StringVar(3) = "123456789"
Execute:
StringVar(3,1,4) = "" "123<NULL>56789"
Results:
StringVar(4) = StringVar(3) "123"
but,
StringVar(3) still = "123<NULL>56789",
so,
StringVar(5) = StringVar(3,1,4+1)
'"56789"
StringVar(6) = StringVar(3) + 4 + StringVar(3,1,4+1)
'"123456789"
