Our app crashes 7.3.2.

[C.T.S.]

We have an application that is supported under OpenVMS 7.3.1., recently one of our clients upgraded to 7.3.2. without notifying us and some of our apps modules crashed their system. This is a great app but built in the 80's, so we actually do not know if just compiling our app under 7.3.2 should do the job, being our app a driver based app.
Any advise is welcomed!!

by driver based app do you mean a device driver? There are various changes in VMS V7.3-2
internals which could affect it

See the new features manual
http://h71000.www7.hp.com/doc/732FINAL/aa-rv8xa-te/aa-rv8xa-te.HTML

and there release notes
http://h71000.www7.hp.com/doc/732FINAL/6668/6668PRO.HTML

The developers of your application should read both.

Thanks, we will, although we have gone through tons of stuff and documentation that came with our update for 7.3.2 and 7.3.3. but then again, we will go through any docs that are out there that can help us out.
Thanks

Normally in such a case one would do an analysis using the crash dump file to see what went wrong, and if it reflects a problem in your software or in VMS.

Bingo: we are working on this, analysin stack and crash dumps, thanks for the input.

Hello,

just as a heads-up, afaik there are changes to the internal structures included in the up-coming 8.2 release, that you might want to test before one of your customers get bitten. Ian most probably could comment more on this.

Greetings, Martin
