We must now take a small diversion before proceeding on with the rest of the objects and discuss flow-control. The flow-control statements available in RLaB are the if-statement, the while-statement, the for-statement, the break-statement and the continue-statement.
The flow-control statements use a syntax that is similar to
the C-language10.
Braces `{
' and `}
' are required in all of the
flow-control statements.
