Re: Objects on SD card

I thought I had understood, it turned out I didn't :(
1. if I create directories on an SD card using the PC, they're "DOS
objects", let me say, and can't be properly reognized (i.e.,
manipulated, browsed, modified) on the 50G - right?

Yes and no. They are DOS directories, but they can be modified using
3rd party programs.

2. if I create a dir on an SD card, for example by doing:

\<< 1 + \>>
":3:PROGS/MYPROG"
[ENTER]
[STO]

then the PROGS directory on the SD card *should* act as an HP object,
i.e. should be modifiable - instead it is not :(

What has happened here is that you created a DOS directory named
"PROGS" and a variable inside named MYPROG. I imagine you are trying
to make a directory with programs, in which you can see everything
inside. You should understand that the HPDIRs are actually just files
containing objects. The calculator doesn't have any sort of "folder"
system like with FAT32. It just has routines able to access and
display the various items zipped together.

There are three things you could do. First, make a variable that
contains a list of all the programs in your "PROGS" directory. You
can then recall this to see what is there. 2nd, try using some more
advanced code that will list items from the SD card. 3rd, go all out
and use the HPGCC filesystem which has no such limitations.
