Mid Function

Office VBScript

Microsoft® Visual Basic® Scripting Edition Mid Function

Description

Returns a specified number of characters from a string.

Syntax

Mid(string, start[, length])
The Mid function syntax has these arguments:

Part Description

string String expression from which characters are returned. If string contains Null, Null is returned.

start Character position in string at which the part to be taken begins. If start is greater than the number of characters in string, Mid returns a zero-length string ("").

length Number of characters to return. If omitted or if there are fewer than length characters in the text (including the character at start), all characters from the start position to the end of the string are returned.

Remarks

To determine the number of characters in string, use the Len function.
The following example uses the Mid function to return six characters, beginning with the fourth character, in a string:
Dim MyVar
MyVar = Mid("VB Script is fun!", 4, 6) ' MyVar contains "Script".
Note The MidB function is used with byte data contained in a string. Instead of specifying the number of characters, the arguments specify numbers of bytes.
