! Can somebody please help???
! The following is a small piece of code in Think C 4.0.
! Why can't I get it to work?
! 
!   #define SFSaveDisk    0x214	/*low memory global*/
!   myCInfoPBRec   myInfoRec;
!   Str255         directoryName;	
! 
! 
!   myInfoRec.dirInfo.ioNamePtr = directoryName;
!   myInfoRec.dirInfo.ioDrDirID=MyCurDir;  /* from SFGetFile as in DTS SC 018 */
!   myInfoRec.dirInfo.ioFDirIndex = -1;   /*directories only*/
!   myInfoRec.dirInfo.ioVRefNum =(-*(short *)SFSaveDisk);
!   error=PBGetCatInfo(&myInfoRec,false);
!   if (error != noErr) SysBeep(10);
! /*I was making a few changes here, but even when they were
! removed, the problem didn't go away*/
!   error=PBSetCatInfo(&myInfoRec,false);
!   if (error != noErr) Debugger();
! 
! When I run this code, no error is detected on the PBSetCatInfo call and
! the CInfoPBRec appears to be correctly filled in, but PBSetCatInfo
! returns error=FFD5 a fnfError (file not found).  Does anybody have
! any idea why?  This has been driving me crazy for hours!!

I assume you meant "no error is detected on the PBGetCatInfo."  The problem
is that the ioDrDirID field is interpreted by PBSetCatInfo as the dirID of
the PARENT directory, whereas PBGetCatInfo accepted and set the dirID of
MyCurDir.  Thus, between the calls, set ioDrDirID from ioDrParID.  And don't
feel bad, that is far from clear in IM IV.
