of the fields in the input file.

Defaults to
".new" pasted on to the name of the input file.
separator
string giving the desired separator between fields in the output file.
blanks.out
flag to cause trailing blanks in the output fields to be eliminated.

but with the separator string inserted to separate fields.
This file is then ready for input via

at least in the sense that it has a known field separator.
