Select - Case

Executes one of several groups of statements, depending on the value of an expression.
When using a Select-Case statement always put the most likely candidates at the top of the list. This will help performance.
If you use only one instruction per case you can put the instructions on the same line using a colon.

Select Case sText 
   Case "Match 1":  Call Proc1() 
   Case "Match 2":  Call Proc2() 
   Case Else:       Call Proc3() 
End Select 

If you want to execute more than one instruction then put the instructions below the case statement.
You can combine a series of tests in a single case statement by separating them with commas.

Select Case X 
   Case 1 To 5 : statement 1 
   Case 6, 7, 8 
      statement 2 
      statement 3 
   Case Is = 6 : statement 4 
   Case Is >= 12 : statement 5 
   Case Is > 8 And Is < 11 
      statement 6 
      statement 7 
   Case 10 To 15, 15 To 20 : statement 8 
   Case "better": statement 9 
   Case Is < "A" : statement 10 
   Case Is > "solutions": statement 11 
   Case Else: statement 12 
End Select 

If no Case expression matches the value of the identifier than execution continues at the statement following the End Select
Similar to numbers, text values can also be grouped.
The default or when Option Compare Binary is specified is a case sensitive comparison: A < B < Z < a < b < z

This cannot be done

Case Is > 8 Or Is < 11 

Nested Select-Case

Select Case statements can be nested, as long as each Select Case has a corresponding End Select.

Switch

The SWITCH function returns values based on expressions.
This provides an alternative to the Select-Case.
