     I am the same person that is discussing this with you on GEnie.  I
will take it up there.  You seem to respond faster there.:-) No. No. and
No. to your suggestions.

: 
: If that doesn't help, post your code!

    I would but since you are the only one responding to this it would be
useless to have you see it twice.  I will get you the 4 or five line code
that you asked for on GEnie.  (Still kinda curious why you needed me to
write 4 lines of code and 17 lines of data? Heck I could do it from memory
or just cut and past from the post on GEnie.;-) One open call and the data
needed and then one big "rtl" for a shell file and one "dc i2'0' " to break
into GSBUG.  But hey I am easy.)
