I appreciate the suggestion, but that led to a new problem, four gawk
error messages:

gawk: cmd. line:1: ORS=1?,:\t
gawk: cmd. line:1:             ^ parse error

               (The caret lines up with the comma on the first line.)


gawk: cmd. line:1: ORD=1?,:\t
gawk: cmd. line:1:              ^ backslash not last character

                (The caret lines up with the backstroke on the third
line)

I'll take another look at this later today.
Again, thank you; appreciate the effort.
