Telon is delivered with a large number of execution-time subroutines. Source code is provided for some, but not all. Changing environment parameters causes different subroutines to be called, and often the new subroutines behave differently to the old. This severely limits your ability to change environments while continuing to use Telon, and also hampers your ability to eliminate Telon and maintain your programs at the COBOL or PLI level.
CASE Integrators Corp. can provide you with all required subroutines, customized to emulate any other environment. All our subroutines are delivered as source code. About 95% of the code is COBOL, the rest assembler. This will allow you to regenerate your programs to run in a different environment
Field edits make up the simpler group of Telon subroutines. Source code is provided for these routines, but use of them requires a Telon license. CASE Integrators Corp. provides a complete set of tested replacements so you can run your legacy Telon programs without a Telon license.
Merge routines are a more complex issue. There is a complete set of these routines for every target environment and every line optimization setting. No source code is provided for these, and the different sets are not compatible. Quite frequently, a program whose production version writes underscores to a field will write blanks if the target environment or line optimization setting is changed. On input, the field contents may not be returned at all. Without the expertise we have developed over the years, these issues may well prevent you using your legacy systems without continuing to pay for a Telon license you no longer want.
