6. Minimum Code
  All FaceWare modules are shipped with "example" or "demo" programs that illustrate use of the modules.  These programs have a one- or two- letter prefix that designates the associated module:  "vDemoXY" illustrates use of ViewIt, "drDemoXY" of DrawIt, "dbDemoXY" of DocuBase, etc.  ("XY" is a compiler designation defined in the "About Compilers" program).  Most such demo programs are quite small (2-4 pages) due to their use of FaceIt & ViewIt to automatically handle most menu and window events, and therefore make a good starting point for new projects.
  Before you explore the vDemoXY (ViewIt) and fDemoXY (FaceIt) demo programs, it is helpful to examine a program that represents the minimum amount of code necessary to open a ViewIt window in a FaceIt-based program.  This code is presented below for the 3 major languages supported:

• Pascal
 uses FaceStorLP, FaceProcLP;        {C1}
 begin
 fRec.uName := 'Minimum.Rsrc';       {C2}
 FaceIt(nil,DoInit,0,0,0,0);         {C3}
 FaceIt(nil,NewWnd,1000,1,0,0);
 repeat
  FaceIt(nil,DoLoop,0,0,0,0);        {C4}
  if (fRec.uMenuID = 1000) then
   ...
 until false;
 end.

• C
 #include "FaceStorLC.h"             /*C1*/
 void main()
 {
 strcpy(fRec.uName,"Minimum.Rsrc");  /*C2*/
 FaceIt(0,DoInit,0,0,0,0);           /*C3*/
 FaceIt(0,NewWnd,1000,1,0,0);
 for (;;) {
  FaceIt(0,DoLoop,0,0,0,0);          /*C4*/
  if (fRec.uMenuID == 1000)
   ...
  }
 }

• C++
 #include "FaceStorSC.h"             /*C1*/
 void main()
 {
 strcpy(fRec.uName,"Minimum.Rsrc");  /*C2*/
 FaceIt(0,DoInit);                   /*C3*/
 FaceIt(0,NewWnd,1000,1);
 for (;;) {
  FaceIt(0,DoLoop);                  /*C4*/
  if (fRec.uMenuID == 1000)
   ...
  }
 }

• FORTRAN
 include FaceStorLF.inc              !C1
 record /FaceRec/ fRec
 common/FaceStuff/fRec
 fRec.uName = 'Minimum.Rsrc'         !C2
 FaceIt(0,DoInit,0,0,0,0)            !C3
 FaceIt(0,NewWnd,1000,1,0,0)
 do while (.true.)
  FaceIt(0,DoLoop,0,0,0,0)           !C4
  if (fRec.uMenuID = 1000) then
   ...
 end do
 end

The "C#" comments refer to later help topics that describe what the associated code is doing:
  C1 = see Include Files topic
  C2 = see Resource Files topic
  C3 = see Initializations topic
  C4 = see Event Handling topic
Please take the time to read these topics so that you have a good idea why FaceIt-based programs are built around these four elements.
