Re: HP 11c with HP15C's manual Message #8 Posted by Vieira, Luiz C. (Brazil) on 10 July 2003, 9:25 a.m., in response to message #7 by unspellable
Hi, unspellable;
I own one of each: HP11C and HP15C. Using the HP11C with an HP15C Owner's Hanbook "in hands" is not hard at all, but some resources described in the HP15C's manual are not applicable to the HP11C, of course. Except for the four extra major enhancements found in the HP15C, being Complex Numbers handling, Matrices arithmetic, numerical SOLVE and Integration, both share the following equivalent points:
- math resources for real numbers, including trigs, logs and hypebolics
- stastics functions and ressources are the same for both, but there is a difference related to statistics registers location: in the HP15C the block is defined between R2 and R7, and in the HP11C it is located in registers R0 to R5;
Some of the differences are:
- memory handling, organization and availability: the HP15C has the equivalent to 67 registers (469 bytes) against 21 registers plus 63 program steps (210 bytes) in the HP11C available for the user
- register arithmetic in the HP11C is limited to [STO] operation [R0 to R9 and RI]; the HP15C goes far beyond this
- the hP15C allows RCL RAN# (Randon pseudo-generator seed) and the HP11C does not
- programming resources differ in three aspects:
relational operators - the HP15C has twelve and need TEST n function to access ten of them, while only ten are available in the HP11C
[LBL][.] n, [GTO][.] n and [GSB][.] n are not available in the HP11C
flags - the HP11C has general-purpose flags 0 and 1, while the HP15C has general-purpose flags 0 to 7; flags 8 and 9 in the HP15C have specifc meaning and application;
- [SCI] and [ENG] in the HP11C are not defined for eight and nine digits
I feel as if I'm missing something, but these are the raw differences and equivalences. Reading HP15C Owner's Handbook when using the HP11C demands taking these facts into account.
My 2˘.
