Yes I admit that my code is not 100% bullet proof but it covers me
most of case I need.
Georg, I'm afraid if your code would run 100% well on all common DOS
and DOS-clones and Windows DOS boxes, maybe yes I donn't know. Here's
output of your code ran under DOS box of XP under DOS Navigator:

I can see here some overwritten strings (MCB:7FD0) and strange
characters (MCB:85C0)
