HP41CX, ext mem prob...



#6

Hi there.

I have managed to save a program to extended memory with a non-printing character at the end of the name. Don't ask me how I managed it, I have _no_ idea. Well, the problem is that I cannot now purge the offending file, I just get 'FL NOT FOUND' each time, even though I use <backspace> in Cat4 to put the name directly in the alpha register.

Does anyone have any suggestions as to how I can remove this file without fritzing the whole of memory?

Many thanks in advance.

Dear JasonG

for deleting the program-file find out the file position number in X-Memory. Enter this number to X-Register. Now execute EMDIRX which places the file name in ALPHA-Register. Last execute PURFL for deleting the program file from X-Memory....

Hi Christoph,

EMDIRX does not exist in the standard X-Functions module.
I suspect it to be in either the X-I/O or the X-IL module.

Regards,

Hi;

EMDIRX is exclusively available in the HP41CX; maybe you'll find other equivalent in a non-standard HP41 module (e.g. HEPAX). X-IO does not have any, and... X-IL? I only know X-IO for the HPIL; is there any other? I'm curious.

Many thanks...this worked. :-)

Incidentally, I don't understand why the Cat 4 & backspace method to get the file name into the alpha register didn't work properly (no odd character at the end of the filename) but the EMDIRX method did...any ideas?

Regards

JasonG
