DOSCREEN.PAS is a turbo-pascal program that does the most primitive
part of screen generation.

It produces two output files

1> a .PAS file which contains two procedures that will be a big part of
   Full-Screen IO programs. Their syntax and names match those of Borland's
   B-TREE.Pas sample program that was distributed with Turbo-Toolbox.
   These procedures are:

     -- OutForm: Prints the prompts that will appear on the screen in their
                 proper locations.

     -- ClearForm: Erases anything written in the entry fields, but leaves
                   the prompts intact.  This may seem trivial, but the
                   co-ordinates of the gotoxy statements contained here will
                   be the coordinates to start whateve input routines you
                   write.

     -- Also included in this .pas file is a "main program" which will
        compile under Turbo, and serve as a test of the outform procedure.
        You'll almost certainly want to throw the "main program" away once
        you've incorporated the routines into your program.

 2> A .SCR file which contains the screen in the same format as DOSCREEN
    stores it in memory which makes it accessible for further editing.  it
    too can be thrown away when no longer needed.

DOSCREEN Editing Commands - Basically follow Wordstar except:
  Fixed 8 space tabs only.
  Going beyond the a border of the screen takes you to the other side.
  i.e. Exceeding the right margin takes you to the left side of the next line;
       Exceeding the bottom margin takes you to the top and vice versa.
  There may be one or two other exceptions.  You can have fun expanding
  or changing these.

SYNTAX:  Field tags can contain any character except '_'.  They may
contain up to two consecutive spaces.  Changing the procedure FormStrings
can change any of this.  Field Data Entry Blanks should contain only
'_' characters -- even if you intend to use others as in date fields.
(e.g. __/__/__ should be handled in Doscreen as ________  When you write
you input routines you can change them).  The only purpose of these '_'
as far as DOSCREEN is concerned is to count the number of spaces to blank
out.


-----------------------------------------------------------------

GETTING STARTED:

You may get a 'whiff' of this program's capabilities by doing the following:
1> RUN the file SAMPLE.PAS

2> Compile Doscreen.pas under turbo to a .COM file.

3> RUN Doscreen:  Immediately press Ctrl-F.  This will bring up the
   sample screen for editing.  It should look Identical to the one you
   just saw when you ran sample, except for the lines of '-' at the top
   and bottom of the screen.

4> Now edit the screen however you like, saving it to whatever file you
   like.  If you call it 'SAMPLE', however, the original sample will be lost.

As you can see, this program may serve as one building block in a
DataBase type program using the Turbo ToolBox.  That was my intention.


I'd like to see any questions or improvements anyone wants to make in
