Syntax

CASE <expression> IS

WHEN <constant1> => <instructions>

WHEN <constant2> => <instructions>

WHEN <constant3> => <instructions>

END CASE

Description

The CASE instruction allows you to choose one of several sets of instructions according to the value of an expression.

The CASE instruction may appear in a PROC, SCENARIO, INITIALIZATION, TERMINATION or EXCEPTION block.

The list of options for the expression begins after IS and ends in END CASE.

WHEN identifies the different constant expressions that cause a specific process to be carried out. This process is defined by the instructions following the => symbol.

OTHERS processes all the values of expression that have not been explicitly processed in the CASE. This instruction set is optional.

<expression> must take an integer value.
