-----------------------------------
Processes commands based on a condition.
-----------------------------------

In this structured programming command, <expL> is evaluated.  If <expL>
is true, then any statements following the IF and prior to either a
matching ELSE or ENDIF (whichever occurs first) will be executed.

If <expL> is false and ELSE has been included, then any statements after
the ELSE and before the ENDIF are executed.

If <expL> is false and an ELSE has not been included then all statements
between the IF and the ENDIF are ignored.  In this case, the program
will continue with the first statement following ENDIF.

IFs may be nested within one another provided that each IF has a
matching ENDIF.

Comments may be placed on the same line after IF, ELSE and ENDIF.  These
comments are ignored during program execution.

Clauses
-------

<expL>
        If <expL> is .T., <statements1> is processed.  Otherwise, <statements2>
is processed.
