Mid Function

Returns a specified number of characters from a string.

Syntax

Mid(string, start[, length])

Arguments:

• String: String expression from which characters are 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:

Example 1:

Dim MyVar2
MyVar2 = Mid("BSL is fun!", 4)  
'Output: "is fun!"

Example 2:

Dim MyVar
MyVar = Mid("BSL is fun!", 4, 6)  
' Output: " is fu"

Example 3:

Dim MyVar1
MyVar1 = Mid("BSL is fun!", 20, 6)  
' Output:  ("")

Example 4:

Dim MyVar
MyVar = Mid("BSL is fun!", 3, 6) 
' Output:  "L is f".

Example 5:

Dim MyVar3
MyVar3 = Mid(Null, 4, 6)  
' Output: Null
