It will backup all objects in the current directory into the SD card, into the same path where they are in HOME, each object in a different file, overwriting them if they exist. Doesn't do subdirectories, though, you have to manually enter the subdirs and run it there too.

Code:


\<< PATH TAIL "/" SWAP ADD "/" + \GSLIST VARS ADD

Hi Claudio,

I entered the above program into my Hp50g, with the appropriate \ char substitutions. Ie \GS char(133) from CHARS.

When run in home I get the error:

ADD Error: Invalid Dimension

And on return stack:

2: "/"
1: { }

Mode is set RPN
Cas approx
Can you see whats wrong?

PATH TAIL will give you an empty list, so it can't be used at HOME without considering that as a special case (which the code does not).
The whole point of that little program is to dump an entire subdirectory into an equally named subdirectory in the SD card, so it's only meant to be used within a subdirectory.

To make it work in home a simple fix would be:

Code:


\<< PATH TAIL IF DUP SIZE THEN "/" SWAP ADD "/" + \GSLIST ELSE DROP "/" END VARS ADD
VARS 2. \<< RCL SWAP 3. \->TAG DUP PURGE STO 0. \>>
DOLIST DROP
