Next Generation Calculator

One would like Fortran 2003's version of array handling with the fancy list stuff from Lisp.

Access to big memory and a nice screen would be good (as would multiple skins).

It should still act as a calculator rather than a C or Lisp or Fortran or Algol2021 (if this exists) as these are not suitable for quick setup computations; they need some preparation to get started. (However, perhaps allow the calculator to call C or Fortran or Pari...)

EMU48 for Android does support the 50g with all built-in functionality. The only limitation is that EMU48 emulates the Saturn processor, not the ARM. Therefor you cannot run programs written with HPGCC.

If you want "fancy list stuff" there is ListExt which greatly extends the list processing functionality of the 50g and is very fast. In terms of general-purpose programming languages it is comparable to Python's Itertools package or the data.list package for Haskell.

Other useful libraries/programs are GoferLists (similar to ListExt, older but several useful commands) and LSORT (orders of magnitude faster than the built-in SORT). Both are available on hpcalc.org.

Though not compatible with EMU48, Pari/GP is available on the Play store. I'm not a big fan of it's programming language but it is very fast.
