HP50g Global variables scope

[vq]

I'm a new user of HP50g, so maybe a basic question. I want to have some trivial programs in Home directory, some of these programs need to use values stored in global variables. It's easy to do with the variables stored in Home, but then Home directory has too many entries and it's quite confusing. I would like to have a subdirectory, e.g. "MYVARS" to store the global variables. How can I access these variables from a program running in Home directory? I could do it the opposite way (to have variables in Home and run the programs in a subdirectory, then the variables are accessible - but I'd prefer the first setup).
In general, is it possible in UserRPL to address a global variable really globally, something like fully qualified file names (including path) on a PC?
Thanks

How about a structure like this:

Home

DIRs ... CASDIR

EXAMs ....Projs

EXAM.1

PROG ... VAR1 VAR2 VAR3 VAR4

|

Prg1 Prg2

Say, Prg1 uses VAR1 and VAR4, Prg2 uses also VAR1 plus VAR3

The variables are up in the PATH so they a used directly

when their names are not quoted eg. VAR1 instead of 'VAR1'

When you STOre into a variable "one floor up"

you can use something like this:

<< PUSH UPDIR 15 'VAR1' STO POP >>

where PUSH poushes you flags and current PATH to a variable

ENVSTACK in CASDIR, where they are POPped ...OR

<< PATH -> p << UPDIR 15 'VAR1' STO p EVAL >> >>

actually you could leave the PATH result in the stack

and do some manipulations to get it out of the way

and to bring it back to the top of stack for EVAL

Alternatively you could have the directories reversed:

Home

DIRs ... CASDIR

EXAMs ... Projs

EXAM.1

VARs ... Prg1 Prg2

|

VAR1 VAR2 VAR3 VAR4

Now recalling goes like this:

<< { VARs VAR1 } RCL >>

STOring:

<< VARs 15 'VAR1' STO UPDIR >>

You could have other variations 

like using variables from below, same level and UPDIR

anyway anything higher on your PATH

will get executed by a simple reference with no quotas

whether the name refers to a program or a variable

Variable 'execution' will just recall the contents

that is, if the 'name' contains a value

string, complex number, matrix, algebraic, list, library

BUT

if the contents are: a program, CODE, etc, it will be run

it's just like using the command line and pressing [ENTER]

more..?

Thanks for the hints, I'll experiment a bit to see which method suits me most.
