Hi all,

After working with R and other languages I have to do some work in Perl and it's giving me a headache.. I pass 3 parameters to my subroutine. Depending on the variable the script can change their value and the final section prints a custom XML script. But no matter what, the script will not work because of the local/global variables. How can I use the variable within a loop only when the 'if' condition is met and if not then use the pre-defined one?</p) 

sub ddd {

a = $_[0];
b = $_[1];
c = $_[2];

if ($a == '1') { $a = 'p'; }
elsif ($a = '2') { $a = 'pp'; }

if ($b == '3') { $b = 'w'}

print v "  < $a >  < $b > < $c >";

}

Probably not the most elegant code but since there is so many variables I cannot make too many loops and start adding more variables as the code will grow too much. Any other way to do it?

Thanks for all your help.

Tom
