HP-67/HP-97 Compatibility 41
Programs that call more than three subroutine levels on the
HP-67/HP-97 will not function the same way on the HP-41C.
The HP-41C accepts subroutine calls up to six levels deep.
When merge is followed by a pause in an HP-67/HP-97 card
program, once translated the pause is not useful. The HP-41C
always stops and prompts for a card when programmable read
functions are executed in programs.
The pause length on the HP-67/HP-97 is extended by any key-
stroke.(PsE] on the HP-41C is continued onlyif the keys pressed
are normally used for data entry (e.g., numbers, ALPHAs,
R etc.).
Asthe result of the standard deviation function approaches zero,
the validity ofthe result decreases. For standard deviations near
zero the HP-67/HP-97 could give meaningless small values. In
these cases, the HP-41C displays OUT OF RANGE and program
execution halts.
HP-67/HP-97 write data will be translated to a standard HP-41C
(woTa]. Programsthat do not do standard sequential writes ofthe
primary and secondary storage registers will not execute prop-
erly.
Programs that merge data using the HP-67 I-register will not
operate properly. The HP-41C uses and the X-register for
similar purposes.
HP-67/HP-97 data or program cards cannot be merged.
When the HP-41C automatically switches from fixed notation to
scientific notation for the display of small or large numbers, the
number of digits displayed is determined by the current fix
format (FIX O through FIX 9). The HP-67/HP-97 uses SCI 9 for
this purpose.
The HP-41C compatibility function reformats just-
keyed-in numbers before printing them on the optional system
printer. The HP-97 function prints the numberjustas it
was keyed in.
