Getting different paths in Red language

Question

I am trying to get different paths in Red language. If I cd to /myfolder and run following command:

/myfolder$ /path/to/red.exe /path/to/myscript.red

How can I get these 3 paths from code in script?

I tried:

system/options/path        ; Gives path/to/myscript
system/script/path         ; Gives none
call/output "pwd" outstr   ; Gives path/to/myscript
what-dir                   ; Gives path/to/myscript

I am able to get only one path. How can I get path of red.exe and path of current working directory (In Red language- not Rebol)?

Note: this is related to my question on Rebol at What-dir reporting own directory as current directory in Rebol

In Rebol (2 & 3), this is how you can get those three paths:

system/options/boot    ;; /path/to/red.exe
system/options/path    ;; /myfolder
system/script/path     ;; /path/to/myscript.red

At this moment only system/options/boot in Red matches what Rebol does here.

From the GUI Console:

boot             string!       {C:\ProgramData\Red\gui-console-2017-11-30-4300.exe}
home             none!         none
path             file!         %/C/ProgramData/Red/
script           none!         none
cache            file!         %/C/ProgramData/Red/

From the cli:

boot             string!       "C:\ProgramData\Red\console-2017-11-30-4430.
home             none!         none
path             file!         %/C/Users/Old%20Man/desktop/
script           none!         none
cache            file!         %/C/ProgramData/Red/

Using the GUI Console:

system/options/boot   ; Red binary
system/options/path   ; current dir
system/options/cache  ; Red default dir "home"

system/options/boot is a string!, so you'll have to convert it with:

to-red-file system/options/boot
