Creating if-else constructs
The if-else construct can express single decisions and multi-way decisions by including
elif statements in the construct.
If-else
The syntax for constructing if-else expressions is:
#if time( expression )
statement
#else
statement
#endif
The #endif part is mandatory and the #else part is optional.
For syntax of a time expression, see “Specifying Time Expressions” on page 242.
Elif
The #elif expressions are evaluated in order. If any expression is true, the associated
statement is used, and this terminates the whole chain.
The
#else part handles the default case where none of the other conditions are
satisfied.
When you use
#elif, the #else and #endif parts are mandatory.
