HP50G SD card STO and RCL

I would RCL a directory onto the stack and save it to the sd card thinking the programs inside the directory would be included on the sd card. I will try creating a global variable first on the sd card and then store the programs into it.

If you are trying to use

:port_number:dir_name/prog_name

that's not going to work. The scheme only works for internal ports because the objects stored on internal ports are HP objects. The file format of an SD card, however, is the same as that on a PC, which would have no ability to recognize composite HP objects. Thus the scheme above would not work for port 3 (where the SD card sits) because any "name" you create there is a "PC filename" and any object you store there is no longer an HP object but a "PC file."

Saving each individual program to its own file on the SD card will work just fine, though.
