Hi All,
I want to check if a sub routine that I am calling returns a value
or not.
This is how my code is
$str = function(parameter)
sub function
{
........
......
........
}
the sub routine function in turn uses many other function. Some of these
functions have a return statement and some do not.
So, when i invoke the sub routine "function" and i pass the returned value into
$str, I need to check if $str has any value assigned or not.
Can you tell me how I could accomplish this?
Thanks,
Vijay
