Re: How to access Hash of hashes with multi-dimensional Array

[TomDLux]

If you have a problem figuring out how to deal with data structures, run the program in the perl debugger, then figure out bits one elevel at a time. I used a simpler structure than yours, cause copying it was work. ( -d is the debugger flag. if you don't specify a file, you need to specify an immediate expression, -e. 'mo' is meaningless garbage which generates an error, but makes for a useful mnemonic)
