177 CHANGED: Runtime Environment
--------------------------------------------------------------------------------

     In Clipper 5.0, the runtime configuration options (as controlled by
     the CLIPPER environment variable) of a Clipper-compiled program
     have been enhanced to provide you with more control over how your
     application runs.  The following are the major areas of change:

     1.  You can now specify runtime environment settings on the
         application command-line as well as in the CLIPPER environment
         variable.  To do this, invoke the application program in the
         following manner:

         C><app> [//<setting> ... ] [<app arguments>]

     2.  You can now specify configuration settings with a colon to
         separate the CLIPPER parameter from its associated argument.

     3.  The V and R parameters available under previous releases are no
         longer supported.

     4.  The E, F, and X parameters are basically the same as in
         previous versions.

     5.  The following list summarizes the new CLIPPER parameters:
