Hi guys....

1. I am trying to form a sequence with letter DA of width 100..

2. I want to restrict the occurrence of 'DA' in this 100(characters) to 20%, 30% and so on...

i.e 

DADADDDADDD

[download]
There are 3 DA's in the string...

I want to have control on occurrence of DA and generate sequence randomly for 100 characters 

#!/usr/local/bin/perl
my @chars = ('A','D',);
my $string = join '', map $chars[ rand @chars ], 1 .. 100;
    while ($string =~ /DA/g) { $count++ }
    print "There are $count DA's in the string \n ";
print $string ;

But i am not able to have control on the occurrence of 'DA'

It keeps changing randomly with this coding
