Selecting one or the other with the If...Then...Else statement
The block statement If...Then...Else specifies conditional
execution of either one group or another group of statements, depending
on the value of an expression. Each statement group is usually just
one short statement, since the entire If...Then...Else statement must
be written on one line.
Making a choice with the Select Case statement
The block statement Select Case specifies conditional execution
of one group of statements selected from one or more groups, depending
on the value of an expression. It is similar to the If...Then...ElseIf
statement.
