Re: Address space proliferation

The queues aren't the issue - we're happy to have them all run at the same priority. The application is designed to use a producer : consumer pattern where recovery process(es) act as the producer(s) and this is the consumer. Use of the queues means that there's no I/O - this is acting as an MITM

Re: Linear search vs binary

Leaving aside hashing and suchlike, we've used this for a while in multiple places. It's a ripoff of the C binsrch algorithm in the Tenenbaum data structures book, so there's nothing ~that~ proprietary about it. I edited it to take out our specific stuff, so check carefully as I may have

Glad you got some use out of it. It's a pretty simplistic implementation, but sufficient for our needs. Although based on how rapidly the discussion veered into other languages I thought I'd missed your point somehow. Sent from my iPad On Oct 23, 2013, at 9:43 AM, Dougie Lawson

Re: Linear search vs binary

Someone at our place came up with a fairly slick solution for this about 30 years ago. Design was to get around paging and a desire to not allocate multiple buffers for a dynamic table in a TP system. Another one we use daily. One large block. Key data is pulled from the record and built into a

Re: Subtasking program

It's called a producer consumer pattern. It's directly applicable here - the producer creates the work and the consumer(s) process it. Consumers can either be in separate address spaces or attached subtasks. It doesn't matter for purposes of what they are doing. You - as it says below - link

Re: Table Searchig with a Mask

The time to do compares is likely to pale into insignificance compared to looping around a two dimensional unsorted array, unless the sizes are trivial... I'd be inclined to have a cli/clc pair for each element. I'd also be thinking hard about sorting or indexing the array being searched.
