help with understanding a snippet

[bazz]

HI,

I have a code which uses DataDumper. I am trying to work out how it does what it does, so that I can develop it to do a bigger thing. (read the sub dirs of 6 dirs, instead of from just 1).

Can any of you, please, tell me what this means?


&printHash(\%contruct, \%contruct, '');


I know that it's an instruction to run a sub but I don't understand the rest of it.

It's called "Pass by Reference".

Read about it here (about 2/3 down).

You can also do a google search for it and find lots more info.
