The directory data is written directly into A$. The next version will let you specify which string to use though.
You have 2 functions, roughly equivalent to 'find first file' and 'find next file'.
If A$ is not defined or empty when you call 'find first file' then the contents of the current working directory will be returned.
If A$ contains a relative or absolute directory path, then content from the appropriate directory will be returned.
If the requested directory is empty, then A$ will be untouched and USR will return 0 which indicates no files are present. Otherwise A$ will contain the name of the first file or sub-folder and 65535 will be returned.
Now you should repeatedly call 'find next file', which will return 65535 and a name in A$, else 0.
Job done!
'find first file' = 16514
'find next file' = 16516
Example program follows. I am considering making a code suite for memory at 8K. Or REM. Or above RAMTOP. Or just relocatable so you can stick it wherever you want
