Aye, there be dragons here.  Or worse.  "Abandon hope all ye who here
enter" pops to mind.

It is an effort not to be undertaken lightly as the Law of Unintended
Consquences (previously known as "unpredictable results may occur")
definitely applies.  If you start ripping out (replacing) one CSL routine
you will undboutedly find yourself replacing others: Open, Close, Read,
Write are all related, expecting to find the same infrastructure in the
background.

IBM spent a lot of time & money writing those CSL routines, so it is only
fair that if it was hard for us that it be hard for the next person, eh?
