Writing SQR Program Part 1

SQR --- Structured Query Reporting tool.

SQR Program is divided into 3 parts.

1. Header Section -- Report Title/Report Time/Report Name etc fit into this section.
2. Body   Section  -- Main Program logic goes into this section.
3. Trailer Section  -- Page Number etc will go in this section.

Remember Line 1 of Header section is different from Line 1 of Body section. That means each section of the program has its own memory area.

Lets see how to write program with these sections.

BEGIN-HEADER
END-HEADER

BEGIN-PROGRAM
END-PROGRAM


BEGIN-FOOTER
END-FOOTER

Example:
Reference of below program is from peoplebooks.
begin-program
   print 'Hello, World.' (1,1)
end-program
begin-heading 1
   print 'Tutorial Report' (1) center
end-heading
begin-footing 1
   ! print "Page n of m" in the footing
   page-number (1,1) 'Page '
   last-page   () ' of '
end-footing

begin-heading 1 means Header requires 1 line of space for printing Title.
