Hi, all:

I have a simple work task: input from keyboard a name with two values(its concentration and volume) and then print out a table that shows list of names with their concentration, volume, total yield(con*vol), how much for 30ug/50ug(30/concentration).

I don't know how to create a hash with two values from STDIN, and here is the one I put those in the program.

#!/user/bin/perl
# RNAi_cal.plx
use warnings;
#use strict;
my $yield;
my $thirty_ug;
my $fifty_ug;

#my %RNA;
#print "Please enter RNAi name, concentration:\n";
my %RNA=(
        Ash2        =>"1.85",
        Ja2_1    =>"1.89",
        Ja2_2    =>"2.49",
        Set1_1        =>"1.55",
        Set1_2        =>"2.88");
        
my %vol=(
        Ash2        =>"150",
        Ja2_1    =>"150",
        Ja2_2    =>"100",
        Set1_1        =>"150",
        Set1_2        =>"100");
        
print "\t Con\.\t Volume\t Total yield (ug)\t 30ug\t 50ug\t \n";

for (keys %RNA){
    $yield=$RNA{$_}*$vol{$_};
    $thirty_ug=int(30/$RNA{$_}*100)/100;
    $fifty_ug=int(50/$RNA{$_}*100)/100;
    print "$_\t $RNA{$_}\t$vol{$_}\t $yield\t \t\t$thirty_ug\t $fifty_
+ug\t \n";
}

Many thanks.
