Remarks

 

LEN will always make a copy of the string expression passed as parameter.

 

Use StrPtrLEN to avoid string copy in case of big strings like in the following example:

 

'---Define a 100Mb string

Dim MyString As String = String$(100000000, chr$(0))

MSGBOX 0, "Size: " & StrPtrLEN(STRPTR(MyString))
