Parsing data from shell script to fortran

[SuOraiste]

Hello

i'm trying as a test, to parse some data from a shell script into a fortran script.
I want to do this with a namelist. Here is what I've got so far

SHELL SCRIPT:
#!/bin/bash

cat > CTLFILE <<EOF
&CTLLIST
name="myname",
age="myage" /
EOF

gfortran -ffixed-line-length-none -Wall -o namelist.x namelist.f
./namelist.x < CTLFILE

exit

FORTRAN:
PROGRAM namelist

IMPLICIT NONE

CHARACTER (LEN=6) :: name
CHARACTER (LEN=5) :: age

NAMELIST /CTLLIST/ name, age

PRINT*,name," ",age

END PROGRAM namelist


This procedure should work but the program just simply outputs an empty string, just a space.

any sugestions in what i'm doing wrong.

thanks

You forgot to load the name list in reading firstly the file CTLFILE :

      ...
      read(*,nml='CTLLIST')
      PRINT*,name,"  ",age
      ...

Ok it worked, thanks! BUT only with this syntax

READ(*,CTLLIST)
PRINT*,name," ",age


without the "nml=".
Does your suggestion work for you??

Yes it works with nml=... with a recent Fortran compiler (F90 or later). But the keyword nml is effectively optional, probably to maintain a compatibility with older F77 compilers.

Ok, now I got it!
It must be NML=CTLIST, without ' or "".

I was wondering because I'm the gfortran version I'm using is the version which comes with the latest ubuntu release, which is pretty recent.

Well, that help me alot anyway. thanks!

Yes you are right the apostrophes have to be deleted... Sorry for the typo.
