How does one specify the last assembly level location displayed in
dbx ?
In adb the dot - "." does it. When I want to dissassemble 10 instructions
from the last location displayed I do:
.,10?ia
In dbx the following prints the 10 instructions from the current location:
(*(&$pc))/10i
but I don't know of a way to display an additional 10 instructions.
According to the dbx Man pages:
address / [count ] [ mode ]
Display the contents of memory starting at the first
(or current) address up to the second address, or
until count items have been displayed. If no address is
specified, the address following the one displayed most
recently is used.
so it seems like /10i should do it. Unfortunatly dbx interprets / as the
search command and looks for the string "10i".
Any pointers will be apreciated,
Dror
