Yes, unlike C and C++ , = is used in both cases and the situation makes the
difference, kind of.
Now I want to create a While

I GUESS (without knowing for sure) that you could make a function that
returns the value of your InStr statement AND gives that value to the
Position variable.
Such as:
While MyInstr(i, ProcessString, " ")
blah blah blah
Wend
function MyInstr(a As Integer, b As String, c As String) As Integer
Position=InStr(a,b,c) ' I am not sure if your Position variable is
available within a function however, but I think it is.
MyInstr=Position
end function
Or something like that, I don't know the exact syntax for InStr at the
moment.
It appears this doesn't work. I wanted to evaluate the function InStr and
