** Revision History in reverse order:
**
**  The following changes were incorporated in the 07.01.90 release:
**
**  06.16.90 -  Cosmetic and misc changes: (BOSSDEMO.C,
**              MAKELIB.BAT (LC6), include memory model directives
**              for Lattice 6.XX batch files).           
**              Thanks again to Bill Hinkle.            (V5.17)
**
**              QuickC 2.5 Support.                            
**
**              MSC 6.0 Support.  Changed "windows.h" to CAST
**              NULL as an int.
**              (windows.h)                                    
**
**  04.04.90 -  wn_help was taught to use wn_putsa to enforce user
**              specified help screen attributes.  Tip of the hat
**              to Chris Madsen.
**              (wn_help.c)                             (V5.16)
**
**  03.23.90 -  Added "wns_escape". This is set to TRUE by wn_input
**              whenever ESCAPE has terimated the input.  ESCAPE
**              now terminates input for all input field types.
**              (wn_gbool, wn_gdate, wn_double, wn_gfloat, wn_gphone)
**              (wn_gtime, wn_guint, wn_gulong, wn_gint)
**              Thanks Dexter!!                         (V5.15)
**
**  03.12.90 -  Due to popular request, wn_open now range checks
**              the window parameters to make sure that the window
**              will actually fit on the screen.  NULL is returned
**              if not.  This will prevent some cockpit "bad handle"
**              error exits.
**              (wn_open.c)                             (V5.14)
**
**  03.08.90 -  Added wn_hlinit, wn_help, wn_popup, and wn_qpopup.
**              These functions are close clones to the old sample
**              code provided in help.c and popup.c.  HELP.C and
**              POPUP.C will no longer be distributed.
**              (wn_help.c, wn_popup.c, windows.h)
**              (genindex.c)                            (V5.13)
**
**  03.07.90 -  Placed all "externals" in "windows.ext".  This is
**              being done to ease the burden of making changes
**              to both global and external data.  This will also
**              keep all the constants in one place.
**              (windows.c, windows.h, windows.ext)     (V5.12)
**
**  03.06.90 -  HELP Key is now user definable.  The global wns_hkey
**              has been added and defaults to F1.  This global
**              can be set directly of via the wn_shkey() function.
**              (windows.c, wn_init.c)                  (V5.11)
**
**  03.04.90 -  Added wn_stitle (Supertitle).  wn_stitle provides
**              (top, bottom) (centered, left, right) titles!
**              wn_stitle.c                             (V5.10)
**
**  03.03.90 -  Added wn_gatext - get ascii (ANY ascii text).
**              Now you can input graphics characters!
**              Tnx to Werner Schonber for the suggestion.
**              wn_gtext.c                              (V5.09)
**
**  03.01.90 -  Fine tuned overlap detection to improve performance.
**              wn_activ.c                              (V5.08)
**
**  02.25.90 -  Shadow window support. wn_activ.c, wn_close.c,
**              wn_move.c, windows.h, windows.c, wn_open.c 
**                                                      (V5.07) 
**
**  02.24.90 -  Eliminated most of the assembler functions.  This
**              was done to provide better support for the HUGE
**              memory model.
**              (c:{wn_bios, wn_mouse, wn_sup}, *.asm)  (V5.06)
**
**  02.04.90 -  Linked exploding windows to time of day clock.
**              Added wns_gticks() in wn_open.c.
**              nap() in BOSSDEMO now uses wns_gticks.
**              (wn_open.c)                             (V5.05)
**
**  02.03.90 -  wn_sdelspc was not handling requests to delete 
**              trailing and leading spaces from strings that were
**              only spaces!  Tnx es a tip-o-de-hat to Pat Elam,
**              M. G. F. Gilliland, M.D., and Harold Jackson.
**              (wn_string.c)                           (V5.04)
**
**  01.28.90 -  wns_movscr was not allowing for 132 column or
**              wider screens.  It was taught how to allocate memory 
**              for user defined physical screen sizes.  Thanks to the
**              folks at Atomic Energy of Canada LTD. 
**              (wn_sup.c)                              (V5.03)
**
**           -  v_cls() in "wn_bios" was taught about wni_mxrows 
**              and wni_mxcols. 
**              (wn_bios.c)                             (V5.02)
**
**  01.20.90 -  Pulldown code in BOSSDEMO would not work if called
**              twice.  The problem was traced to the "winopn" member
**              of the static structure mainbar.  Setting "mainbar.winopn"
**              to FALSE before "wn_close(mainbar.wpsave)" in "pddemo()"
**              solves the potential problem.  Thanks to Russ Brown for
**              reporting the problem. 
**              (bossdemo.c)                            (V5.01)
**
**              Version conversion table:
**              
**                   Base Release    Base Version
**                      ??.??.86        1.00
**                      ??.??.87        2.00
**                      ??.??.88        3.00
**                      ??.??.89        4.00
**                      ??.??.90        5.00        
**
**  The following changes were incorporated in the 02.15.90 release:
**                         AKA Version 5.00
**
**  01.10.90 -  WCVLIB.ASM created.  This file contains the assembly 
**              language routines for WATCOM 7.0.  Previous versions of
**              WATCOM should use MSVLIB.ASM.  
**
**  01.05.89 -  Physical windows wider than 80 columns were not 
**              working correctly.  Thanks to all who reported this
**              problem. (wn_actic.c, wn_sup.c, windows.c, wn_init.c).
**              The constant "4096" was not removed in wn_savres. It
**              does not impact the physical sceen size logic but does 
**              allow the code of those who have "tinkered" with video 
**              pages to continue to work.
**
**  12.22.89 -  Re-assembled all assembly language routines to insure
**              that wni_mxcols, wni_mxrows, and wni_mxneed were being
**              used correctly.
**
**  11.30.89 -  ZORTECH 2.0 Support.  Please note that ZORLIB version
**              2.0 can not create a usable LWIN.LIB.  Microsoft's LIB
**              works fine and should be used.  ZORTECH has been notified
**              of the problem.
**
**  11.24.89 -  jeesh... One line exploding windows exploded again!
**              This time we got the gremlin!! Tnx to Michael Canfield
**              for suppling the test case.
**
**  (11.15.89)  **
**
**  10.28.89 -  Modified wn_title to insure ALL compiliers process
**              hex values that are imbedded into the title properly.
**              (e.g. "Hello \xcd There!")
**              Thanks to Don Wahl for pointing out the discrepancy.
**
**  10.25.89 -  It would appear that the PC/PC_CLONE BIOS can not deal 
**              with scrolling single line windows.  wn_insrow() was taught 
**              to erase single line windows and avoid using the 
**              BIOS for this special case.  This problem does not exist
**              on AT or PC/2 class machines.  Thanks to Harold Jackson
**              for reporting the problem.
**
**  10.24.89 -  Eliminated a potential multiple cursor problem with
**              the mouse cursor when a window is being saved/restored
**              with an active mouse.  Tip of the hat to Steve Thatcher
**              of Attachmate.
**
**  10.20.89 -  Corrected a bug in wn_open to allow 1 line exploding 
**              windows to function properly.  Thanks to John F. La Fleur 
**              for reporting the problem.
**
**              wn_puts was not handling borderless windows properly.
**              Thanks to Tim Keane for reporting the problem.
**
**              Lattice Version 6.0 Support
**
**  09.27.89 -  Logic was added to wn_input to insure that user supplied
**              non null editing buffers are the same lenth as their masks!
**              This logic will prevent garbage from appearing when 
**              wn_input is called to peform data entry with a prefilled
**              value in the user buffer (ubuff).
**
**  09.05.89 -  The forms package now treats the ESCcape
**              like most common applications do.  That is to say that it 
**              causes the current operation to cease.  Current 
**              Window BOSS users please note that this feature can
**              be disabled by removing the code in wn_frmget that contains
**              "ESC.001" as part of the comments.
**
**  09.05.89 -  Added 1st character sensitivity to the sample popup menu
**              code. ** NOTE ** -> For menu's that have different 1st
**              character picks.  
**              
**  (08.25.89)  **
**
**  08.23.89 -  Exploding window opens were failing on SOME 
**              adapters.  Even size exploding windows were
**              failing. Corrected!
**              Thanks to Richard Allen for his assistance.
**
**  The following changes were incorporated in the 07.01.89 release:
**
**  06.17.89 -  Lattice 3.41!! ... The version release race is on!
**
**  05.29.89 -  Mix Power C 1.30 Support.  
**
**  05.25.89 -  Added wn_gutext and wn_gltext.  Get upper case only
**              and lower case only text functions.  Thanks to
**              Charlie Munao for the suggestion.  Improved code 6/6/89.
**
**  05.23.89 -  wn_frmcls now sets the form pointer to the form being
**              closed to NFRM and the individual field pointers to
**              NFLD. This should help those who attempt to dectect
**              if a form/field is active.        
**
**  05.10.89 -  wn_close now sets the window pointer to the window 
**              being closed to WNLPTR.  This should help those who
**              attempt to detect if a window is open.
**
**           -  Moved definition of FAR MEMORY marcos from "wn_sup.c"
**              and "wn_activ.c" to "windows.h".
**
**  05.06.89 -  By popular request... WN_FRMGET now displays both the
**              field prompt and data entry mask for all fields prior
**              to accepting input for the 1st field.  Accomplished by
**              introducing "wni_frmflg" which is used/tested by
**              all the data entry functions, wn_input, and wn_frmget.
**
