Is it possible to store and recall numbers as with other HP
calculators? Are there storage registers for this and how to use
them. Thank you

Hello Jon,

Suppose you have the number 123 on the stack
'A' STO
puts 123 in the storage registre 'A'

'A' RCL will recall the number 123 on the stack

have a look at this very well done video wich explain all of this and
the usage of 'softmenu' on 48/49/50 :

Nota about the video : You dont have to 'unlock' alpha mode before
clic 'ENTER'

As has already been written, The HP48/49/50 line of calculators
permits you to create named variables, each containing any built-in type of object
(not just real numbers), and since one type of object is itself a "directory"
of additional variables, you can arrange all your variables into a set of
nested directories, much like files on a computer disk.

Older-style calculators used only numbered registers,
each containing one real number (or in some cases a short string),
and left you to remember for what you were using each register.

However, since the HP48/49/50 line of calculators
includes lists, vectors, and even matrices as built-in object types,
in which each element has an index number (starting with 1),
you can use each such single object with a numeric index value,
to address each individual element in the collection,
without having to create so many named variables, e.g.:

{ 0 0 0 0 0 } 'A' STO @ create a list [of any objects]
[ 0 0 0 0 0 ] 'A' STO @ or create an array [numeric on 48G series]
123.45 'A(1)' STO @ store into any element
'A(1)' EVAL @ recall an element
