R4A for Android & linux?

[lab...@gmail.com]

Pending Cc: to comp.lang.forth

Thanks for R4A, which I'm trying to use to access the hidden inners
of my Android Tablet.

Editing the tail of procedure/word ": Main "
in /storage/emulated/0/r4/r4/dev/editors/gestos.txt
to add the 2nd-last line:
verde "Trace GREENLINE " print
is confirmed, when I tap "gestos" on the <running screen>.

? Since /storage/emulated/0/r4/r4/dev/editorscrayon.txt
has procedure/word "loadfile "
what files of the file-tree can R4A read,
and what is possible R4A code to confirm,
via eg. a minimal output/trace of the file read by `loadfile` ?
-------
Since the documentation shows:
" Registers A and B, for address memory and peek and poke values

>A | a --
A> | -- a
...
Move and fill memory

MOVE | de sr cnt -- Copy CNT dword from SouRce to DEstination
...
Memory and Files

MEM | -- dir Start Free memory
LOAD | d "filename" -- e Load file in memory
SAVE | d n "filename" - Save memory in file
..."
? do these functions refer to the memory of the VirtualMachine and
the real files of the AdroidDevice ?

? Can I access the Android's fileSystem including the
external/mounted SDcard ?

These changes are not in the android version, if you have the availability to make the executables I can help you to add the latest modifications. Although it is possible to translate to the words that I modify.

 

Move and fill memory

MOVE | de sr cnt -- Copy CNT dword from SouRce to DEstination

MEM | -- dir Start Free memory
LOAD | d "filename" -- e Load file in memory

yes, I guess

 

? Can I access the Android's fileSystem including the
external/mounted SDcard ?

I guess yes, I use fopen, fwrite,etc  from C using the ndk access in android,

see https://github.com/phreda4/r4MV/blob/master/r4a/jni/r4android.c

 

I have a problem when make the apk for android, this apk recreate a folder in memory for work,
