#-- NAME: KJV_Bible_SDBM.pl (or compiled to .exe)
#--
#-- AUTHOR: Eric Hansen U.S.A
#--
#-- DATE: August 29, 2017
#--
#-- LANGUAGE: Win32 Perl - ActiveState ActivePerl v5.6.1, binary build 638
#-- Win32 GUI Module (by Aldo Calpini) release 1.02
#--
#-- COMPILER: IndigoSTAR Perl2EXE v5.03, Win32 Perl Application Compiler
#--
#-- FUNCTION: KJV Bible Navigator Software. FlatFile/SDBM Database Version.
#-- DB User-Interface is a TreeView/RichEdit set of GUI widgets.
#--
#-- DATABASE: 3 input Files (JOINT DATABASE TECHNOLOGY - ISAM/NoSQL):
#--
#-- KJV_Bible_SDBM.dat (16,037 KB) Fixed-length(528 characters)
#-- records (no CR/LF), Flat File of 31102 KJV Bible verses
#-- extracted from a total of 66 books and 1189 chapters.
#-- KJV_Bible_SDBM.dir (4 KB) SDBM Binary File (part 1 of 2)
#-- KJV_Bible_SDBM.pag (128 KB) SDBM Binary File (part 2 of 2)
#-- Both used for random access indexing within the Flat File
#-- to the byte offset of the first verse within each chapter.
#-- Verses within a Chapter are read sequentially from there.
#-- These 3 files (named as shown) must reside in the application
#-- directory with program file KJV_Bible_SDBM.pl or .exe
#-- if compiled to a standalone executable.
#--
#-- OUTPUT: KJV_Bible_Genesis_Chp_3.rtf would be a Rich Edit (Wordpad) output
#-- file created in the Program/Application DIR containing all the
#-- verses for the Book of Genesis, Chapter 3. This output file is
#-- automatically created for each Book&Chapter the end-user selects.
#--
#-- HASH: Format of SDBM tied to hash table BibleIDX (for Books 1 to 66)
#-- KEY VALUE DESCRIPTION
#-- =============================================================
#-- ...
#-- 10 II Samuel,2Sa,24 Bk10 = name,abbrev,nbr_chps
#-- 10|1 4236144,27 Bk10|Chp1 = offset,nbr_verses
#-- ...
#-- 10|10 4351248,19 Bk10|Chp10 = offset,nbr_verses
#-- ...
#-- 10|24 4589904,25 Bk10|Chp24 = offset,nbr_verses
#-- ...
#--
#-- ABORTED: Should the program abort, run from a command prompt to see error.
#-- This would most likely occur if one or more of the 3 database
#-- files are missing from the application directory, or they have
#-- been renamed.
#--
#-- NO VERSES
#-- DISPLAY: If you do not see Bible verses displayed in the RichEdit widget
#-- after you have DBL-clicked your mouse on a particular chapter
#-- within the TreeView widget, it is likely due to the associated
#-- *.rtf output file already existing and having been manually
#-- set to a READ ONLY status. If the file exists, it must have
#-- WRITE permission. An Error Msg Box will pop up on the screen.
#-- To correct this problem, either delete or rename the
*.rtf file.
#-- If you wish to write personal notes within any of the *.rtf
#-- files generated, and prevent them from being stepped on
#-- (i.e. overwritten), then instead of making the file(s) READ ONLY,
#-- simply rename them. Example:
#-- KJV_Bible_Genesis_Chp_3.rtf to
KJV_Bible_Genesis_Chp3_Edited.rtf
#-- Or, you can make a subdirectory and store your edited files there
