Large 50g program example

[Tugdual]

While I am convinced that calculators are not supposed to have large programs (or it means you didn't pick the right calculator) I wonder what a large RPL program would look like and how Hp thought we should approach that. With the absence of gosub equivalent, we are left with two options: deep nesting or fragmentation of code into multiple sub applications. Hp calls variables "objects" for the reason that you can store anything in a variable, including fragments of RPL code. Providing that a program is made of multiple objects, does this conceptually mean that the equivalent of a program is a directory? Is that the way we're expected to approach large programs structuration?
