hi, thanks for answering
I suposse the matter is the malloc sentence shouldn't fail if I have 15 MB =
of extended memory available and I'm asking for 19200x1920 ....=BF? or it s=
hould ..., then I showld have more than 15 MB RAM, because my system has; i=
s there any way to have more RAM available using DOS Box? cos if I don't us=
e DOS Box the music sounds incorrectly
Could you explain me how to use CWSPARAM? will the available RAM grow up wi=
th the -x param? I see the problem is the memory size
thank you
Pablo

This usually means the program is trying to touch to memory it should not b=

touching (such as a null pointer).=A0 Under most DPMI providers you can tou=

the first 4096 bytes of memory, but with CWSDPMI it is protected to catch=

usage of NULL pointers.=A0 Before running your application,
issue the command: cwsdpmi -x and then run the program.=A0 If the problem g=
oes=20
away it is a bug touching memory it should not, but you can either
use the -x qualifier, or use cwsparam with flag 4 to disable it permanently=

Of course, it would be better to fix the buggy program, but whatever works
for you.
