Hi,

I overcame a problem which displays warnings while executing perl program, the situation is 

sub compare{
  $param=shift;
  print "String" if($param eq "5");
}

[download]
In the above case the $param may be a string or integer and in case if it is a integer then, we will usually get a warning saying cannot do a string comparison for the integer value .

so can this be avoided ,is there a way to check if $param is integer of string and based on that do a string or integer comparison? Like we do a check for Ref("ARRRAY")?

Regards
