                     QBOL DEMONSTRATION PROGRAMS

The QBOL demonstration programs are designed to show a typical small
QBOL application.  The data file that they operate on has 100 records
of 128 characters each.  The data file records are described by the
QBOL source code in NAMFIL.RS.  

The first program is used only once to build a dummy file of records
with the two digit record number repeated in each field.  The records
are boring, but good for testing.  The file building program is called
LBUILD.   Execute it by typing QBOL LBUILD.QB in response to the OS/78
prompter dot.

The second program, and the best commented one, is NETRPT.QS.  This 
program prints a simple report similiar to a payroll report.  It uses
simple calculations to derive line and column totals.  The report would
normally continue for all of the records in the file, but is limited 
to the first 25 for the sake of brief demonstrations.

Another typical and useful printing program is one which prints
name and address labels from the same data file.  The user has the
choice of how many labels to print on one line, as if for special
forms with sticky backed labels.  This program demonstrates direct
file accessing in its ability to begin printing with any record.

A very simple form of file editing program is provided with LEDIT.QS.
This program prompts the user for a record number, fetches that record,
displays it on the screen, and allows the user to change most of the
fields in the record.  There is no error checking on the data in each
field, not even checks for the delete character.  The input routines
are set up to expand them for more detailed editing in the future.

When compiling, note that the file NAMFIL.RS must be present on the 
same device as the source code.  This file becomes part of the source
being compiled via the INCLUDE statement.

When executing, note that the data file NAMFIL.DT must be present on
device DSK:.  Some programs have error trapping routines to tell the
user that the file is not available, programs without the error trap
would halt with a monitor error and return to OS/78.
