Mid Function

Description

Returns a specified number of characters from a string.

Syntax

Mid(string,start[,length])

The Mid function syntax has these parts:

Part	Description

string	String expression from which characters are returned. If string contains no valid data, 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.

Note

Another function (MidB) is provided for use with the double-byte character sets (DBCS) used in some Asian locales. Instead of specifying the number of characters to return, length specifies the number of bytes. In areas where DBCS is not used, MidB behaves the same as Mid.

Example

This example uses the Mid function to return a specified number of characters from a string.

MyString = "Mid Function Demo"    ' Create text string.
FirstWord = Mid(MyString, 1, 3)    ' Returns "Mid".
LastWord = Mid(MyString, 14, 4)    ' Returns "Demo".
MidWords = Mid(MyString, 5)    ' Returns "Function Demo".
