Re^2: Perl beginner's issue with hash

Thanks so much for this! Just as a quick follow-up, do you have any thoughts why I might be receiving an error when I change the 'if' to a 'while' statement? All I've changed is the 'if' for a 'while', but then the following appears when I try to run:

syntax error at step_two_redux.pl line 19, near "else"
syntax error step_two_redux.pl line 28, near "}"
Execution of step_two_redux.pl aborted due to compilation errors.

All I've changed is the 'if' for a 'while' ... If all you've done is change `if (CONDITION) { ... } else { ... }` to `while (CONDITION) { ... } else { ... }` then yes, this is a syntax error because there is no `while ... else ...` statement block structure in Perl. (The only `if` ~~statement~~ \| statement block I can see in the OPed code is `if (/$id/g) { ... }` — is this the one you're referring to?) I'm not sure what you were trying to accomplish with this change, so I'm not sure what to advise as the proper change. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]
