SELECT CASE...CASE...CASE ELSE...ENDSELECT

These commands implement a multiple conditional jump. It is a question of verifying whether a given expression, supplied as first, is equal to the various expressions that will be gradually registered through the CASE statement. If they are, the code following the CASE statement will be executed. Otherwise, we will move on.

If the CASE ELSE statement is given, it will be executed if there is no other match. It follows that it must be placed last.

The code executed is always and only the one between the CASE that satisfies the condition and the next one (or the CASE ELSE). The code on CASE ELSE will be execute always and only if other matches fail.
