Hi.

This uses gfortran to write TAB characters:
Code:
#!/usr/bin/env bash

# @(#) s1       Demonstrate Fortran-90 writing TAB characters.

# Utility functions: print-as-echo, print-line-with-visual-space, debug.
# export PATH="/usr/local/bin:/usr/bin:/bin"
pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
db() { ( printf " db, ";for _i;do printf "%s" "$_i";done;printf "\n" ) >&2 ; }
db() { : ; }
C=$HOME/bin/context && [ -f $C ] && $C gfortran

FILE=${1-one.f90}

pl " Input data file $FILE:"
cat $FILE

gfortran $FILE
pl " Results, plain:"
./a.out

pl " Results, showing invisible character representation:"
./a.out |
cat -vet

pl " Results, showing invisible character representation, eliminate blanks:"
./a.out |
sed 's/ //g' |
cat -vet

exit 0

producing:
Code:
$ ./s1

Environment: LC_ALL = , LANG = en_US
(Versions displayed with local utility "version")
aix 7.1.0.0
bash GNU bash 4.2.10
gfortran GNU Fortran (GCC) 4.6.3

-----
 Input data file one.f90:
program f1

! @(#) f1       Demonstrate Fortran-90, write a TAB character.

character*1 :: tab
tab = " "       ! a real TAB character between quotes
write(*, "(f7.3,a,f7.3,a,i7)") 1.0, tab, 2.0, tab, 3

end

-----
 Results, plain:
  1.000   2.000       3

-----
 Results, showing invisible character representation:
  1.000^I  2.000^I      3$

-----
 Results, showing invisible character representation, eliminate blanks:
1.000^I2.000^I3$

See man pages for details.

Best wishes ... cheers, drl

binfmtf95-interpreter

binfmtf(1)							     binfmt_C								binfmtf(1)

NAME

       binfmtf-interpreter - binfmt_misc fortran handler

SYNOPSIS

       binfmtf-interpreter fortran-source-file-name [command-line opions ...]

DESCRIPTION

       binfmtf95-interpreter  compiles a fortran source file specified on the command-line using the gfortran compiler, and executes the resulting
       file.

       It is designed to be used as a handler for binfmt_misc handler, which is a system used in Linux for handling arbitrary  files  as  executa-
       bles.

       The command-line options are passed on to the compiled binary.

FILE MAGIC

       There is a requirement for Fortran source files to have the magic characters ! BINFMTF95: at the beginning of the file.

       That line also is used to specify the additional command-line options for Fortran compiler.

ENVIRONMENT

       GFORTRAN
	      The compiler used.  The default is to use gfortran

       BINFMTCTMPDIR

	      Temporary directory used for binary and execution.

	      Falls back to $TMPDIR $TEMPDIR or /tmp

       BINFMTC_DEBUG
	      enables debug output if set.

       BINFMTC_GFORTRAN_OPTS
	      Additional Gfortran options.  Use BINFMTC_DEBUG to verify the options being passed on to gfortran.

	      The default is  -O2 -Wall
