HP41 ASCII File Sort Routine? Message #1 Posted by Paul S. on 24 Aug 1999, 12:34 a.m. I would like to sort an ASCII file in extended memory, some 100-150 records. I was wondering if anyone ever wrote/came across a routine to do this. My records are all 24 bytes long and I need to sort the entire length. I can transfer them to a PC and sort them there and bring them back, but I was looking for a completely 41 based solution. If anyone could point one out for me I'd appreciate it. I suppose I could write one, but it seemed like something someone would have done before. Thanks.

Re: HP41 ASCII File Sort Routine? Message #4 Posted by Chuck Ratliff on 26 Aug 1999, 12:21 a.m., in response to message #1 by Paul S. Dearing's 'Calculator Tips and Routines contains five sort routines: Quick Sort, Stack Sort, Synthetic Quick Sort, Smallest/Largest of 3 Numbers, and Synthetic Alphabetize. The latter is, as noted in another response, from PPC ROM- Wickes, Jarrett et. al. I can send the routines if you wish. Good kuck.
