.np
.rm 68
.m2 0
     This command reads a file "infile" containing tab
characters and replaces them with an equivalent number of spaces
to create a new file "out" which has the same column spacing
as the original file.
The input file has default type ".FOR", and the output file ".DET".
.sp
     The "de-tabbing" operation
is performed by using the DEC Standard Runoff
program to expand the tabs at 8-character intervals, and
then using the DEC SOS Editor to remove the extraneous
carriage-return/line-feed pairs and 3 blank lines
added in by Runoff.
.sp
     Some utility programs cannot correctly interpret tabs in
a file (for instance, the FLECS Preprocessor, the FMT Text Formatter,
and the RENUM FORTRAN renumbering program), so use of
the DETAB command will greatly simplify tab-conversion problems.
