SUMMARY
=======

The IIF (Immediate If) function returns one of two expressions, depending on the
value of a logical expression. When IIF evaluates a logical expression, if the
logical expression evaluates to a logical true value (.T.), IIF returns the
value of the first expression. If the logical expression evaluates to a logical
false value (.F.), IIF returns the value of the second expression.

MORE INFORMATION
================

The IIF function can be used in place of the IF ... ENDIF structure for simple
conditional expressions. This function is especially useful in CREATE REPORT or
CREATE LABEL commands to conditionally specify field contents. In a FoxBASE+ or
FoxPro report or label, the IIF

  function is the only conditional statement allowed. The IIF function

also executes considerably faster than the equivalent IF ... ENDIF statements.

Examples
--------

  STORE 10 TO Num
  Char = IIF(Num > 9, STR(Num, 2), STR(Num, 1))
  ? Char

* This code returns 10.

  Store 9 to Num
  Char = IIF(Num>9, STR(Num, 2), STR(Num, 1))
  ? Char

* This code returns 9.
