 DUMPPROCESS=x in your config.sys. Creates files PDUMP.001, PDUMP.002,
etc. Use PMDF (from devcon or product CDROM) to analyze. 

 Not nearly as useful as it is in MVS. It only dumps the regs and the 
stack. No code or data areas. 

 It is a little more useful under Warp 4, but I have not yet decided 
on how useful it would be without complete source/compile/link reorts 
files. I suspect this will continue to be a developer only (not 
support) oriented facility. 

 Oh.. Check the use of the TRAPDUMP and TRACE facility too.. Although 
not quite what you are asking, it is quite useful in debugging.
