Once upon a time Tom Hammond uttered these sage words to All:

 TH> I'd appreciate a little direction here, if possible.
 TH> My problem is that the program contains some in-line code..

 Ok Tom this program reminds me a lot of a gw-basic program I saw some
 time ago that I derived SPIN.OBJ from by converting the data into a
 BINfile and then disassembling it. As a matter of fact I *think* the
 program you posted _is_ that very same program if I'm not mistaken.
 Anyway, here's what I came up with to get QB compatible 'spin' subs
 for drives A: and B:....

 For those of you that do not have MASM or TASM the next message
 contains a debug script that you can recreate SPIN.OBJ from.
