COBOL Technical Tips

We've learned a lot over more than 30 years of programming, including 20 years of developing applications for the PC.  Hopefully we can make your life a little easier by passing on some of what we've learned.

Download the profiles and macros that we use with Kedit

We've used Kedit as our COBOL programming editor since 1986.  We used to work on an IBM VM system many years ago, and liked the features of XEDIT, the editor used under VM.  Kedit is similar to the mainframe's XEDIT, only better. You're welcome to use the stuff that we have developed to customize Kedit for our COBOL development.

Linking

Linking is one of those things that are problematic for some people, and linking Windows applications can be tricky, too.  This is a good no-frills write-up on what you need to know to get started.

Object Libraries

If you're developing an application of any size, you need to understand and use object libraries.  An object library is just a special type of file that stores all of your object modules in a single file.  It eliminates disk clutter and makes linking much less cumbersome.

Object Library Maintenance

This article shows how easy it is to create an object library and store your object modules in it, using the Microsoft LIB program.  It really is amazingly simple.

Static and Dynamic Subroutines

The differences between using statically linked and dynamically linked subroutines.  Yes, Virginia, there's a difference. 

We also talk about good and bad points of both, and some cautions about using one form or the other. 

Creating DLLs and Import Libraries

How to package a bunch of subroutines into a single DLL and access them using an import library.  It's a very neat trick that uses the best features of static and dynamically linked subroutines.
