Hi all,
   how are u? hope u r all very fine!

   hmmm... just some small questions...
   1) if i declare 2 global arrays as follows...
       char ar1[100];
       char ar2[20];
    will djgpp ALWAYS store ar2 exactly after ar1???
   i.e. will the expression ar2[-1] always return
ar1[99]??

   2) what are registers that i can safely change in
my assembler function without having to push its
values? 
  
   3) in djgpp progs, does djgpp make the register es
equal to ds?? ALWAYS??

   4) i wrote a program today which exited with an
error message being printed repeatedly forever, then
the system restarted! I can't remember the error
message exactly! but, i remember it was sthg like
"Exiting due to Unknown Signal Handler". what does
this mean?

Thanx in advance!

Urs forever,
   Mohamed El Dawy
