   Library eXecute locks into a library file, searches and extracts a COM file 
into memory at 100h, and sets up the various buffers to look like the COM file 
was  executed by the ZCPR3 command processor.   LX parses the command line  as 
ZCPR3 itself would.  NDR references are allowed, the External FCP is loaded if 
available,  etc.   If  no LBR is indicated (by -dir:lbrname),  the command  is 
executed from the ROOT:COMMAND.LBR.  Version 1.0 (8/85) by Richard Conn.

 LX Notes - 1/3 

   a. Vs 2.1 updates (08/13/90, Howard Goldstein):
      - Moved a couple of lines of code so that CPYFLG is initialized properly
        in the type 4 version.  
      - Fixed an  error in LOADCOM that could cause certain type 4 programs to
        be loaded one page too high.  
      - Cleaned up error handler invocation code.  
      - Removed a few  redundant  "and a"  instructions,  changed wording of a
        couple of comments, changed a "jp" to a "jr", etc.

   b. Vs 2.0 updates (08/10/90, Al Hawley, Cam Cotrill, Howard Goldstein):
      - Massive rewrite to  allow  LX to  run  as type 1, 3, 4 and extract and
        load type  1, 3, 4 files.   A  bunch  of  unneeded  buffer  space  was
        removed, ADJMCL was re-written to work "in place".  All address check-
        ing code and  dynamic  load  buffering  is new and improved.  Original
        "look and feel" retained.

   c. Vs 1.9 updates (04/01/88, Bruce Morgen):
      - Adds use of wheel byte as patchable option.  If byte at 102H is set to
        zero, LX will use ROOT:USECMD.LBR instead of ROOT:COMMAND.LBR as 
        default command library, but only if wheel but is reset (e.g., a non-
        wheel user is at the helm).  
      - Adds safety header, corrects help screen
      - Both Default LBR names remain patchable to preference.

   d. Vs 1.8 updates (11/29/87, Howard Goldstein):
      - Rewrote the ADJCML routine.  It now adjusts the command line properly
        when a library name is included in the command.

   e. Vs 1.7 updates (11/21/87, Howard Goldstein):
      - Added code to parse file names  via  resident  CPR  code if  ZCPR33 is
        present.  This makes  LX  completely  Z33 compatible.   Removed  Bruce
        Morgen's in-line  PUTER3 code since  Z33LIB's  version  works properly
        now.
 LX Notes - 3/3 

   f. Vs 1.6 updates (06/04/87, Bruce Morgen):
      - Adds ZCPR 3.3 error handler support, special syntax for chaining from 
        ARUNZ's default alias feature, and fixes console output.

   g. Vs 1.5 updates (04/24/87, Bruce Morgen):
      - Adapted to coexist as  an  ECP with error handling under ZCPR 3.3 and
        BGii 1.13 or later.   Also extended  Michael's  auto-install  code to
        properly initialize the copy routine for Z33 type 2 COMfiles  (origin
        other than 100H).
