Of course, OBGET and OBPUT are vanished, and nothing has come to replace them.
One can disassemble algebraics with OBJ->, or use \v|MATCH, but sometimes you
wished they were there.  Same for EXGET and EXPUT.
What is also missing are the catalogs.  They were rather useful, especially
the units catalog, becuase it knew the full name of all the units.  And: USAG
is not a catalog.
One big missing function is VIEW\^| and VIEW\v|.  Why were these left out?  I
do not always have the memory to edit an object just to see a few more lines.
Well that's my list of missing HP28 features of the HP48.  Anybody else?
