Hi, I would like to know whether the removal of the "dots" from the Dir$("*",DIR) function is intended in the newer (> 5.07) firmware versions.

'************ testdir$ *********
Print "MMBasic version:" MM.Ver
Print "--------------------------------"
DirName$= Dir$("*", Dir)
Print DirName$

Do While DirName$<>""
DirName$ = Dir$()
If DirName$<>"" Then Print DirName$
loop

Print "--------------------------------"

Output for MMBasic version: 5.0706

MMBasic version: 5.0706
--------------------------------
.
..
nsa
--------------------------------

Output for MMBasic version: 5.09

MMBasic version: 5.090006
--------------------------------
nsa
--------------------------------

What happened to the dots and if so why?

I think this doesn't make Picomites more compatible with other previous MMBasic versions.

Regards
Michael

FatFS is used for the SDcard system and does not return these when asked to return directories. In order to maintain compatibility between the A: and B: drives I have suppressed them for the "A:" drive. This is inline with other MMbasic variants (just confirmed on CMM2). Earlier versions of the PicoMite firmware were out of line for the A: drive

if (lfs_info_dir.type & (LFS_TYPE_REG | LFS_TYPE_DIR) && pattern_matching(pp, lfs_info_dir.name, 0, 0) && !(strcmp(lfs_info_dir.name,".")==0 || strcmp(lfs_info_dir.name,"..")==0 )){

Thank you very much!
It's to bad, I've gotten used to it for 40 years.

For me it was very surprising. I don't have an SD drive on the Picomite and I hadn't noticed it on the CMM2 until now. A note in the manual could be useful.
A workaround should be easy to do.
