CASE (CS)
Syntax
CASE (CS)
The CASE; command is the central part of a case statement, which enables multiple
actions selected by the case variable to be specified. This is an efficient alternative to using
multiple DO.WHEN; commands.
The commands used to define a case statement are summarized in the following table.
Command Abbreviation Function
BEGIN.CASE; BC; Start of the case statement
CASE; CS; Case condition
OTHERWISE; OW; Default case condition
END.CASE; EC; End of the case statement
Each command (and all enclosed logic commands) must start on a new line.
A BEGIN.CASE; (BC;) command specifies a data item against which values defined by
CASE; commands are compared.
If any of the values specified matches that of the data item, the following logic (up to the
next case condition) is performed and execution continues from the END.CASE; (EC;)
command associated with the case statement.
The OTHERWISE; (OW;) command can be used to specify logic to be performed when no
other case conditions with the CASE; statement apply.
Case statements may be nested to nine levels deep, including the use of case statements
within the logic associated with the OTHERWISE; command.
