Re: Fetching input character without newline?

My compiler is showing that construction >>>>>>>>>while() <<<<<<<<
it's a syntax error. And I agree with it value in the brackets is
undefined, so what can we do
with it. Not proper usage of while loop. That what I
think!!!!!!!!!!!!!!

#!/usr/bin/perl -w

use strict;

print "Enter your response here (1-5): ";
while(<STDIN>){

if (/^([1-5])$/){
print "\nUser chose $1\n";
last;
};
print "Try again (1-5): ";

First of all read quick reference to regular expressions in perl.
Secound U take '\n' - newline character
with <STDIN> and in /^([1-5])$/ U don't want it. So or :
chomp $ret;<<<<<<<<<<<<<<<<<<<<
or change regex/^([1-5])/ or /^([1-5])\n$/.I already tried that one, and it didn't work. The screen output wraps
as soon as I press <enter> and THEN $ret gets the data from STDIN.
So it's too late to try to undo the carriage return as far as STDOUT is
concerned.

This is why I was hoping for a "magic" input record terminator. . .
one that would cause the assignment from STDIN to complete
without causing the screen output to wrap.
