testcondition Required expression that must evaluate to one of the basic data types,
such as Boolean , Integer , String , and so on.
expressionlist A list of expression clauses representing values for testexpression .
Multiple expression clauses are separated by commas and can take one of the following
Expression1 To Expression2 Used to represent a range of values from Expression1 to
Expression2 . Expression1 must be less than Expression2 .
Is] comparisonoperator Expression
comparisonoperator is used to specify a restric­
tion on the value of Expression .
Expression The expressions in expressionlist can be any data type so long as they are
implicitly convertible to the type of test condition .
Statement s One or more statements that are executed if the testexpression matches
any clause in expressionlist .
else statement s One or more statements that are executed if the testexpression does
not match any clause in expressionlist .
End Select Required to mark the end of the Select Case block.
The following code fragment demonstrates using the Select Case statement to set a variable to
the number of days in each month.
Select Case strMonth
Case "February"
intDays = 28
Case "April", "June", "September", "November"
intDays = 30
Case "January", "March", "May", "July", "August", "October", "December"
intDays = 31
End Select
This preceding code is just a simple example of specifying the number of days in a month, but
does not make any provisions for leap years. More code can be added to the “February”
clause to properly set the number of days in February, as in the following code:
Case "February"
If (intYear Mod 100) = 0 Then
If (intYear Mod 400) = 0 Then
intDays = 29
intDays = 28
End If
If (intYear Mod 4) = 0 Then
intDays = 29
