Re: HP49G Sysrpl help with recalling contents of pointers

Hi , I need some help me with recalling contents of ROM during runtime.

I wish to recall the contents of e.g. C%SIN (supported entry) to the stack
during runtime (in order to modify the composite ) and then use it.

E.g.

:: ' C%SIN recall? CDRCOMP EVAL ;

What would the magic word or procedure for recall? be on the hp49g?

I ask because
C%SIN decompiles to
:: PTR 0FEDA 2DUP %%COSH....;
Where PTR 0FEDA splits a C% (complex) into two extended reals.
In this case I already have two extended reals on the stack, and it would be
a waste of time and accuracy to make it a C% first.

Thanks on beforehand

PS in this particular case the below is a shorter version.
:: ' C%SIN recall? EvalNoCheck ;

One way could be to use Nosy to get the ROM
contents as a string of source code, and then
compile by calling MASD.

Create following as a library routine, lets call it
ROM->CODE:
::
x->A xGETNAME
xNosyRPL$
SEP$NL
DROP
xASM
;

Your example then:
:: ' C%SIN xROM->CODE EvalNoCK ;
