Description

 

Return the length of a string expression in number of bytes.

 

Syntax

 

n = LEN(string_expression)

 

Returns

 

Number

 

Parameters

 

 

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.
