Is is possible to debug real mode applications in OS2 using the protected
mode codeview ?

No, but if you have CV 3.0 then you can load Codeview almost entirely into high memory (under regular DOS). Which means that when OS/2 2.0 comes out you will have a good DOS debugging environment under OS/2, but not until then. +++++++++++++++ "Dont get your hair in an uproar!!!" +++++ +@+++++++++++++ +-----------------------------------------------------+ +++++ +++Western+++++ | Todd Crowe | +++++++Washington+++ | n8840371@unicorn.cc.wwu.edu | +++++++University+++ | TODDC@nessie.cc.wwu.edu | +++++++++++++++++++ +-----------------------------------------------------+ ++++++++++ "Innovate, don't litigate!"

I maybe wrong, but even under OS/2 2.0, real-mode programs are limited to 640K and you cannot reserve extended memory to load DOS CV on it. Maybe with 2.0, the OS/2 protected-mode CV can debug real-mode apps. Lucas

It currently doesn't supply extended memory, but that may change. The current version of CVP will not debug real-mode programs (even in 2.0), but it can use the expanded memory. Todd Crowe
