Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi folks.

According to the manual, page 25, it says the syntax is CHDIR dir$ where dir$ is the directory you want to change into.

I can't make this work.

I have a directory on the SD card called DATABASE

If I try the likes of CHDIR "B:\DATABASE" no error is returned, but I am still in the current directory.

If I try the likes of CHDIR "B:\DATABASE\" no error is returned, but I am still in the current directory.

If I try the likes of CHDIR "DATABASE" I DO get an error(can't find or create directory), but I am still in the current directory.

What am I doing wrong? Manual has no more specifics.....

EDIT: Found out the problem - leave off the drive spec: CHDIR "\DATABASE" works.

Nevermind...Edited by Grogster 2014-07-23

Smoke makes things work. When the smoke gets out, it stops!

Grogster,

I believe that this was covered previously. I think in conversation with Nick Marentes.

I can't remember off hand what the solution is, but I seem to remember it being somewhat like the DOS system, where you need to change the DISK first (i.e. B:) and then CHDIR on the disk where the target sub-directory lives.

[edit] just tried it with DOS-MMBasic. It is just as I suspected:
Change the drive first:

B:

Then the directory:

CHDIR "database"
