 Thanks for the above.  I wondered whether it was possible to get
 proper source and symbolic debugging of assembler files when they are
 (1A) included AS    -- no, that fails to single step assembler parts
 (1B) external AS    -- that also fails to single step.
 (2)  external NASM  -- that also fails to single step.

 You said (1B) would probably work if I put in debug information
 [which I could get by looking at compiler output with a -S switch]
 in there by hand.

 I've tried that, it doesn't work yet.  Any suggestions what I'm 
 doing wrong?   I copied all the debug stuff I find in a compiler
 output file, into the AS file. Still no joy.  What's wrong now?

 Source included, very minimal at 50 lines in all.
 [NOT to mailing-list/newsgroup because of previous hassle and
 flaming, write to me for a copy].
