Whenstartedup,ZSCANdisplaystheversionofZCOMitexpectsandits

own software version. It opens the memory image file and shows whether

the file is from a 32-bit or 64-bit kernel. Note that the memory image file

is of the same layout for both 32/64-bit kernel. Except that the long and

pointer fields are interpreted differently. In 32-bit mode, the 32-bit long

and pointer fields are preceded with a 32-bit padding field (whose value

is ignored). In 64-bit mode, the whole 64-bit field contain a valid value.

The prompt zscan> indicates ZSCAN is ready to accept interactive

commands. If ZSCAN is run from an HP terminal (such as HP2392, or

700/92), or a window emulating an HP terminal, a command stack

facility is available to allow easy repetition of previously used commands ,

and editing of those commands for reuse.

The command stack is displayed by entering / and ZSCAN will display

the list o f most recently used command on the screen. For example:

zscan> /

ZSCAN positions the cursor a t the bottom of the list. Any of the

commands may be reused by positioning the cursor on the desired line

and pressing

<Return>. If the command needs to be changed before

reusing, then it can be modified on the screen before pressing

<Return>.
