[question about why ioDirID is modified in HGetFileInfo]

"When returned from a routine, ioDirID contains the file number of a file;
most programmers needn't be concerned with file numbers, but those interested
can read ..." - IM IV-122

It really is buried away in the docs, but there you have it.  Note also that
you'll end up resetting the dirId after each iteration when doing a directory
search, but you knew that already ;->  It's a hack, but I guess making the
paramBlock 4 bytes longer isn't something they wanted to do.
