Almost a dead cert.

Ah!  They were only unusable because there is another check in write() to
make sure you don't write to a FH > 19.  I found the following code:

8B5E06
3b1e1d01
7208

changed the 72 to an eb, and she worked!

Now "all" I need to do is find similar code in CL.EXE (or it's
components) and I'll be in business.  I hope!  BFN.  Paul.
