It takes data from plain ASCII files in the format date ind_no released where date is the date in one of about 1,000 possible permutations of format, ind_no is an individual mark number between 1 and 9999, and released is an optional field which is 1 if the animal was released after capture, 0 if it wasn't. The program calculates Petersen/Lincoln estimates, Petersen Weighted Mean estimates, Triple Catch, and Jolly-Seber. It has been extensively tested and debugged by our active group of population ecologists here at JCU. At the moment I don't recall the maximum number of sampling dates, but it is on the order of 100. Estimates can be sent to screen, printer, or ASCII data file in a format suitable to read in via SAS. I can email uuencoded binaries if you're interested. I'll have to think a little about releasing source, but contact me if you're interested in either. Ross Alford zlraa@marlin.jcu.edu.au -- "The first thing to tell yourself is not to panic.
