Had earlier stated my problem :
User gives an input to the perl program which next
does some function in a fortran program & finally the
output of the fortran program is passed on to the perl
which finally conveys it to the user.
Thanks to all responses due to which i got an approx
solution to the problem as given under :
##perl program##
#!/usr/bin/perl
use strict;
use warnings;
my($USAGE) = "$0 TEST\n\n";
unless(@ARGV)
{
print $USAGE;
exit;
}
my($x) = $ARGV[0];
my($y) = $ARGV[1];
my $outputfile = "outputfile";
open(OUTFILE,">$outputfile");
print OUTFILE "$x\n$y";
my $res = system("./a.out");
my $resultfile = "fort.2";
open(RESULTFILE,$resultfile);
my $z = <RESULTFILE>;
print "\n$z\n";
exit;
##fortran77 program##
OPEN(UNIT=1, FILE='outputfile', STATUS='OLD')
READ(1,*) X,Y
Z = X + Y
OPEN(UNIT=2)
WRITE(2,*) Z
END
My program is running fine. But i have a small query
in order to improve my program. I want to pass the
user input values to the fortran77 in command line
itself without using any files as intermediate. Can
you please guide the changes i need to do in the
program both of perl & fortran & the exact compilation
statement combining both the programs.
Kindly suggest. Waiting for an early
response..Thanking you..
