Linking With Blinker.
 How to take advantage of Blinker
──────────────────────────────────────────────────────────────────────────────

 If you are using Blinker as your linker then we suggest that you add the
 following Blinker link commands to your link script:

        BLINKER OVERLAY PAGEFRAME ON
        BLINKER CACHE XMS < somecache >

 and perhaps:

        BLINKER OVERLAY UMB ON

 if you do not have a pageframe setup.

 This will speed things up a bit.

 For the ultimate usage of MrDebug we strongly recommend that you use
 protected mode linker and link your application with MrDebug in Protected
 mode. In which case just add the line:

        FILE MrDebug.LIB

 to you link script, before CLIPPER.LIB.

 Extra Information

 The following functions can be used (if they are linked in) automatically by
 MrDebug to provide information within the Memory/Info screen.

      BLIMGRSTS               (Blinker 3.00 and higher)
      BLIVERNUM
      BLISERNUM

 The following function may be used by Blinker when the DOS command is
 called.

      SWPRUNCMD

 When using shelling out to DOS, MrDebug will look for the Blinker function
 SWPSETENV(). If this is found, then MrDebug will add a little MrDebug item
 to the prompt so that you know you are still running under MrDebug.
