Is there a way or technique to account for blank items in a [coll]? For example, if a line of data is banged out into [unpack] and then each outlet to it’s own processing, it needs to see the same number of items in every line, right? Or is there a way around that, other than using a random ‘placeholder’ character and trying to weed it out correctly?

Thanks,
Brian

Just try.

But if the length of the list coming from [coll] is important, you could get it with [zl len] and route your datas to different processing.

Something like:
0, data1 12 important_stuff 15 rarely_used_stuff 22;
Then you can split the list into pairs and use [route] to parse the data appropriately.

I’ve also been known to use send/receive names in conjunction with data in colls. That way you can split the list into pairs and send the data directly to its destination via [forward].

These attribute-like techniques make the order of data in the coll unimportant. But they don’t necessarily help if you want to detect null data.

Remove the [zl rot] if you make it into an abstraction as a [patcheragrs] in a [patcher] will always report the patcher name as the first argument. I hope it helps.
