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 all.

"Merry Christmas and all that bollocks."
- Bottom (TV series)

Are you not allowed to specify the path in filename strings?

Example:





If I change the directory FIRST, then it works fine, but I thought you could specify the path in the string?

Looks like I might be perhaps thinking of something else, but I was sure you could do it like this.......

Merry Christmas Grogs
I found the info below in the Addendum.

OPEN fname$ FOR mode AS [#]fnbr

Opens a file for reading or writing.
‘fname’ is the filename (8 chars max) with an optional extension (3 chars max)
separated by a dot (.). The default directory must be selected first using CHDIR (ie, a path is not accepted).
‘mode’ is INPUT, OUTPUT, APPEND or RANDOM.
INPUT will open the file for reading and throw an error if the file does not
exist. OUTPUT will open the file for writing and will automatically overwrite

It wasn't easy to find. I wonder why it's in the Addendum.

Probably cos this only relates to the MM+, as the standard 170 MM2 does not have native SD card support.

Why am I writing code on Christmas Day anyway?! (rhetorical!)
