Case expression: evaluates to the value corresponding to the first matching case.

The first operand is the value to compare against. Subsequent operands alternate between compare values and result values. The syntax is: case(select_value, case1_value, result1, case2_value, result2, ...)

Deprecated:

This expression is SMV-specific and has no other use.
