COBOL Line Numbering Utility

Despite the 'common wisdom' that COBOL is a 'dead language', according to various sources anywhere from 35% to 50% of business applications are written in COBOL.   I would imagine the dollar value of transactions processed by COBOL programs is relatively high.   So, there is a need for utilities to manipulate COBOL source files.

COBRENUM is a quick and dirty utility to manipulate COBOL source files' line sequence numbers (as shown below).   It was written after a 'post-merger downsizing' and before pursuing a Master's; primarily as an exercise to learn Visual Basic for Windows and developing Help files.   The software (source included for your amusement as SOURCE.ZIP within COBRENUM.ZIP) was developed using Visual Basic 2.0 (VBRUN200.DLL is required, can be downloaded using link below), and the help file was developed using Microsoft's Help Project Editor 1.10.000, Windows Help Authoring Toolkit 6.0, and MS Word 6.0c (F.Y.I. - the path for the WHAT 6.0 template is hard coded within the Help file .rtf source).

COBRENUM's purpose is to insert, remove, or resequence COBOL source file line sequence numbers.   COBRENUM makes a backup of the original COBOL source file, using a .BAK extension (what else?).   If the original COBOL source file was line delimited by LF instead of LF/CR, the resequenced file will be line delimited by LF/CR.

Not all COBOL platforms use line sequence numbers.   As an example, HP3000 COBOL74 and Fujitsu COBOL use line sequence numbers, but HP3000 COBOL85 may not and OTCOBOL does not.  COBRENUM is especially useful when manually migrating COBOL source files from one platform or compiler to another.   It can be used with source programs or copybooks.   As can be seen in the screen shot below, it uses a very plain, simple user interface and will run on anything from Windows 3.x to Win98SE, and Windows XP.   It has not been tested on Windows ME or Windows 2000.   Both COBRENUM and its help file will not execute directly on Win 7 (this is a common problem for many pre-Win 7 applications and device drivers).   However, it will execute on a VMware Player 6.0.3 running Win98SE guest operating system.   Data can be transferred between host and guest operating system using Drag 'n Drop.   COBRENUM does not support long file names.

COBRENUM user interface

To use COBRENUM, just simply download cobrenum.zip, unzip cobrenum.exe and cobrenum.hlp into any directory.   Use the Windows Run Command to execute cobrenum.exe.   There is not a setup available; since this is an extremely simple programmer's utility the user can set it up to run anyway they prefer.   Help is accessible from within COBRENUM by pressing the F1 key.   To remove the program, just simply delete it.
