Meaning |
String_Expression |
String |
No |
Any string expression |
Remarks
LEN will always make a copy of the string expression passed as parameter.
Use LENF to avoid string copy in case of big scalar strings variables
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))
Use CLen to return the number of characters.
