Labeled CASE

The labeled CASE statement executes a choice of statements when the value of the

selector matches a case label associated with those statements.

selector

is an INT or INT (32) value arithmetic expression that uniquely selects the case-

alternative for the program to execute.

case-alternative

associates one or more case-label s or one or more ranges of case-label s

with one or more statement s. The statement s of a case-alternative are

executed if selector equals an associated case-label. Each case-

alternative has the form:

case-label

a signed INT constant or LITERAL. Each case-label must be unique in the

CASE statement.

lower-case-label

is the smallest value in an inclusive range of signed INT constants or

LITERALs.
