It's standard in all the BxAMs. OPEN for UPDATE; READ, WRITE. Easy as cake. Just can't change the length of records or members.
In ISPF's case the profile members are really just long streams of data; which are padded (see the PAD .... PAD at the end) to allow for some growth. Unless the growth exceeds the physical member size, it just rewrites it in place when saving. Thanks to that, ISPF profile datasets neither constantly SD37, nor require massive over-allocation. Profile datasets can be PDSE, and often are these days. As for Unix files, no. BPAM support allows only for reading. I suppose that could change in the future if someone makes it worth IBM's while. sas On Thu, Dec 22, 2022 at 12:11 PM Paul Gilmartin < [email protected]> wrote: > On Thu, 22 Dec 2022 02:03:36 -0500, David Cole wrote: > > >It's pretty clear that ISPF updates its profiles in place. > > > How do they do that? > BLDL; POINT; BSAM WRITE? > EXCP? > > Does it work alike with for PDSE? > > Is ISPF profile in PDSE supported?
