I would like to call a sub where the sub name is the same as the changing file name (as I read each file in the directory). For example, I would like to call sub "allergies" if I am reading the allergies file. I would like to call sub "immunizations" if I am reading the immunizations file. I could add a lot of if statements but there must be a clean way to to accomplist this task. Does anyone have an idea?

The line in the code below is "$file();"

Thanks, Kevin 


# version 1.0

use warnings;
use strict;
use Shell;

my $dir = 'input_files';
die "can't opendir $!" unless opendir DIR, $dir;
while (defined(my $file = readdir DIR)) {
    do {
        print "The directory and file are $dir/$file\n";
        die "Can't open input file $!" unless open IN, "< $dir/$file";
        use File::Glob ();
        while (defined($_ = glob(' IN '))) {
          # print "Hello $_";
        }
        while (<IN>){  # Reading contents of file
          next if (/^#/);
          $file();  #####  File name can be many things
          print "Bye " . $_ ;
        }
    };
}
closedir DIR;

sub allergies {

print "in allergies\n";

}


sub immunizations {

print "in immunizations\n";

}
