However, 71A6h and other LFN functions are not implemented by the various LFN drivers for DOS. I tested _some_ of the LFN functions that were supported by different drivers some years ago. These are the functions I tested (unsorted): 710D, 71A0, 7139, 713B, 7147, 71A8, 716C, 7160, 5704, 5705, 5706, 5707, 71A6, 714E, 714F, 71A1, 7156, 7141, 71AA, 713A Win98 supports all of those and likely some others. Of the test list of functions above, DOSLFN and LFNDOS do not support these: 710D, 71A6, 71AA, 5706, 5707 So, those should all have checks. It seems I did not check StarLFN ... My notes (unconfirmed) say that DJGPP v2.03 calls all of those in the test list, except for these two: 5707, 71AA DJGPP also calls this one, so it should have a check too: 7143 Probably Win98 only: 71A7, 71A9 HTH, Rod Pemberton
