(ladebug) (0x14039134)/X

Great - but how do I examine ***32*** bits in hex?

This is a known limitation.  You can't do it right now.  Use the /X and ignore
the upper half.
855.3ADA9X::BRETTThu Feb 27 1997 17:117
Unfortunately my command was actually going to be

(ladebug) (foo)/100xx

and I can't 'ignore the other half' because I was looking for duplicates.

Will not (foo)/50X produce what you want?  You have to split the output in your
mind, unfortunately.  I am pretty sure this is on our to-do list.
