Hi,
Though this thread is now almost a week old, I thought I'd offer one more
suggestion. How about using this
%people = map { chomp; split } <INPUT>;
in place of
%people = <INPUT>;
To my eyes, it is cleaner than adding an explicit loop.
TMTOWTDI,
Jeff

Subject: open file into hash
Hello. I was wondering if there was a way to open a file into a hash? I know
this works for arrays, but was wondering if I this could be done for a hash
also.
I have a file called people.data, which contains two colums:
jose 2
karen 8
jason 9
tracey 1
Can someone tell me what I am doing wrong here:
=============================================
#! /usr/bin/perl -w
open (INPUT, "<people.data");
%people = <INPUT>;
close (INPUT);
#%people = (
# "jose" => '2',
# "karen" => '8',
# "jason" => '9',
# "tracey" => '1'
#);
print "The value for jose is $people{jose}\n";
=============================================
I expect to return the value of "2", but see the following error instead:
"Use of uninitialized value in concatenation (.) or string at ./new.pl line
14.
The value for jose is"
I am guessing that this is related to opening the filehandle as it works if
I
declare the hash within the script (commented out above).
Any help would be greatly appreciated.
Jose
