Case: Pascal Design Choices

• Expression is any ordinal type (int, boolean, char, enum)

• Segments can be single or compound

• Construct is encapsulated

• Only one segment can be executed per execution of the construct

• In Wirth's Pascal, result of an unrepresented control expression value is undefined (In 1984 ISO Standard, it is a runtime error)

• Many dialects now have otherwise or else clause
