@eawrite[] does not remove EA

[Anton Monroe]

Passing a null string to @eawrite is supposed to remove the EA. Instead, it keeps the EA and sets the length to 0.

set ret=%@eawrite[file,.SUBJECT,the subject]
set ret=%@eawrite[file,.SUBJECT,] <--4OS2 thinks the EA is gone

Rexx shows the whole EA--

set ret=%@rexx[call SysGetEA 'file','.SUBJECT','EAval' ; parse var EAVal EAhdr +2 EAlen +2 EAstr ; say ' [REXX] EA == "'c2x(EAhdr)'" "'c2x(reverse(EAlen))'" "'EAstr'"']

I noticed it because I was getting error messages from FC/2 about invalid EAs when copying files from an NDFS drive. I don't know the 4OS2 EAs were the cause, but FC/2 has not complained since I cleaned out all the empty EAs.

I suspect the fix would be just a matter of passing 0 to DosSetPathInfo? instead of the length of the empty EA header.

A workaround is to use Rexx to delete the EA--

set ret=%@rexx[call SysPutEA "%filename", %EAname,]
