GETPOSTVALIDATE()
 Postvalidate the current Get object
------------------------------------------------------------------------------
 Syntax

     GETPOSTVALIDATE(<oGet>) --> lSuccess

 Arguments

     <oGet> is a reference the current Get object.

 Returns

     GETPOSTVALIDATE() returns a logical value indicating whether the Get
     object has been postvalidated successfully.

 Description

     GETPOSTVALIDATE() is a Get system function that validates a Get object
     after editing, including evaluating Get:postBlock (the VALID clause) if
     present.

     The return value indicates whether the Get has been postvalidated
     successfully.  If a CLEAR GETS is issued during postvalidation,
     Get:exitState is set to GE_ESCAPE and GETPOSTVALIDATE() returns true
     (.T.).

 Notes

     .  In the default system, a Get:exitState of GE_ESCAPE cancels
        the current Get and terminates READMODAL().
