There is one program that will do what I believe you need it for. It is
called DM5. I do not think it is shareware. We use it on our mainframe
UNIX systems, but it works on PCs too and it is small. The person to
contact here would be Dr. William Pearson. I could ask him for you and
post a response if positive.
Take care.
