This may be a dumb question, but why will this loop not end when nothing is
entered in STDIN?
print "Enter Things:\n";
while () {
print "I saw $_";
}
print "The End\n";
If nothing is entered the loop continues.
Output:
I saw red
I sa
I added
1;
Inside sub foo and it didn't work, but I just added it to the end of foo.pl
and it worked!
I don't get it?
But thanks.

I am receiving "/home/users/me/foo.pl did not return a true value at
./program1.pl at line 2"

Hello all,
Can "use" be used in a sub routine that is kept external?
Ex.
Program 1.
#!/bin/perl
require '/home/users/me/foo.pl';
exit;
Foo.pl
sub bar {
use strict;
use fcntl;
use AnyDBM_File;
}
Hello all,
Which DBM modules should be used or is most common, compatible, recommended?
Would this be a good choice for sharing variable data with multiple perl
scripts? Kind of a shared variable database?

Hello all,
I am having a problem with memory parenthesis. In the following piece of
code the pattern matches but the $1 $2 $3 $4 variables are null. I can tell

Hello all,

One, which type is recommended DB_File, GDBM, SDBM, NDBM etc.?
Is it common practice to make use of DBM files? Or should I look into some
other database structure?
Is it a significant performance enhancement over
