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.

I have just upgraded my Ex100 from v5.2 to v5.05.02 and am now getting error messages when using the DIR$() function as follows:

f$=DIR$("*.*",VOL) error:INVALID FLAG SPECIFICATION
f$=DIR$("*.*",DIR no error but sub directories are blank ""
f$=DIR$("*.*") error:SYNTAX

There are 2 sub directories on the SD card plus a volume title. The sub directories are displayed correctly by the FILES command and the CWD$ function.

The function f$=DIR$("*.*",FILE) works, successfully finding all files.

Is it possible that I have done something wrong when loading the new firmware causing this or is there a bug in the latest version?

I don't have an E100/E64 handy but try
f$=DIR$("*",DIR)

The wildcard *.* doesn't find files/folders without any extension.

Thanks TassyJim, that fixes the DIR file search. Perhaps could be clarified in future manuals.

However the error associated with VOL search remains.
I did try f$=dir$("*",VOL) but same error.
