... The Boolean object is an object wrapper for a boolean value. ... JavaScript 1.3: added toSource method . ... If value is omitted or is 0, -0, null, false, NaN , undefined, or the empty string ( "" ), the object has an initial value of false.

As conditional or control statements you have IF in many variants (but essentially not changed from Fortran 77), DO (with some new variants) and the completely new statement CASE . The DO- loop should now be ended with the statement END DO and we no longer need any statement number. In addition, we can use the statement EXIT to jump out of the DO -loop and CYCLE in order to go to the next iteration of the present DO -loop. ... all negative numbers WRITE (*,*) 'Negative number' CASE (0) ! ...

TYPES Trees are represented by two types: entree (enumerated tree) and bitree (bit tree). ... Also, it's possible to match patterns: tree <* treequery treequery >* tree The last two operations return TRUE if the node matches the treequery pattern. ... Example of how to add a node: select entree_next(tid) from dmoz where tid <* '1.2.3.*.0' order by tid desc limit 1; INDICES Type tree supports two types of indices: B-Tree - accelerates operations: <,>,<=,>= and =. ...

The if statement uses the exit status of the given command and conditionally executes the statements following. The general syntax is: if test then commands (if condition is true) else commands (if condition is false) fi . ... Make sure that you end each if construct with a fi statement. if statements may be nested: if ... then ... else if ..... fi fi . The elif statement can be used as shorthand for an else if statement. For example: if ... then ... elif ..... fi . Example . ...
