I dunno. But I find them incredibly useful. they have some quirks, and over the years I've been using dynarrays, I've documented these on my own computer -- I even have a dynamic array test program that I periodically use to test for dynarray quirks. They're weird and unpredictable. However I'll take all the quirks, for the convenience of being able to call setlength (rather than getmem or whatever) -- and moreso, for the even larger convenience of automatic freeing of memory -- including automatically freeing embedded dynarrays and ansistrings! Those two points alone are, to me, worth all the quirks that I have to carefully test and document, and the occasional usage error (e.g. the mistake I made that caused me to start this thread). When I started using dynamic arrays instead of making calls to getmem/freemem, my main project (about 25k LOC now) became substantially simpler and easier to maintain. If you're curious about some of the quirks you can look at my test program, which includes some notes I made to myself after running other tests. http://david9.freepgs.com/fpc/dynamic-arrays.pas But if you don't like them for all their quirks and impurity, then don't use them. I'll be the first to admit that I frequently forget aspects of how they work, and have to refer back to my test program.
