Greetings fellow monks, I'm trying to follow strict programming rules in a particular project I'm busy with, something I don't do often :-) I'm trying to minimise the use of global variables, and only to use local variables in procedures. I now have a situation where I need to pass an entire hash to another procedure. Its easy querying the hash in a global variable, but I'd like this to be done professional. My first attempt failed, which was something like this... 
.
.
&callsub(%hashtopass);

sub callsub
{
   %hashread = $_[0];
 
   foreach $k (keys %hashread)
  {

     .
     .
     .
  }
}

Any idea how I can pass an entire hash as a parameter to a sub? Thanks!
