One method of getting tracebacks written to a file without signalling
involves duplicating the code the condition handler established by
SYS$IMAGSTA uses to map and call the traceback facility.  It is not
real hard to do, but it does involve merging an image into the address
space by calling SYS$IMAGACT and fixing up the vectors etc.  If you
are interested, I will send you the source code to such a routine
(written in BLISS-32 or Macro).
