I'm very new to HoHoL or HoH for that matter. Basically I have a hash of hashes. One of the values of a nested hash is an array of subroutine references that I would like to execute.
I've messed around with replacing the sub routine references with just text values and looping over them for printing and things go alright. So, I'm suspecting that there is a problem in the manner that I am calling the subroutine. I've messed around with different manners of calling the routines as well as just calling the first with &{$HoL{$key}[0]}
which seems to be successful but still produces an error complaining about a "" string being used as a subroutine. I'm just not sure where that is coming from since both keys have arrays with at least one element. I appreciate your advice. Thanks -c In reply to Hash of Hash of Listed subroutines by c
