No and no. There are better ways than using a pipe. Pipes makes sense only w

Benjamin Jeeves,
You can probably figure this out. Try running the code below supplying
whatever file name you choose to save it as for an argument.
#!/usr/bin/perl -w
use strict;
my $filein = $ARGV[0];
print "$filein\n";
open(FILEIN, $filein);
my $counter = 0;
my $counter1;
&start;
sub start
if I do not call build_db then alert will run fine as I want it to so is there
away around this problem. See I need the FILEIN to go though a number of
different sub routes how would I go about this.
