Redirecting"enter" when an external command is running..

perl_mystery has asked for the wisdom of the Perl Monks concerning the following question:

print "Running Script....\n";
my @scriptlog =`perlscript -b -f=$file`;#when this command is running 
+,if the user presents enters the choice picks it up,how to redirect o
+r stop this?
print "\nEnter your choice: ";
my $choice = <>;
chomp($choice);

When the above command "perlscript"is running,when the user presses "enter".I get the following error.Can someone pls suggest how to overcome this?

Argument "" isn't numeric in numeric eq (==) at Blacklisted_ErrorCRs.pl

Change == to eq. But apparently you did show the relevant code here. Peter (Guo) Pei	[reply]

That's not what I want.If i change == to eq,the variable $choice still picks up the "enter",while the script is running ,any "enter" buttons should be redirected so that the $choice variable doesn't pick it.	[reply]

Change line 1 from `print "Running Script....\n";` to `print "Running Script: <big><b>Do NOT hit enter!</b></big>\n";` perhaps ? :-)	[reply] [d/l] [select]
