Slide 78 of 80
Notes:
- The last example (LD) shows the BASENAME, DELIMPOS, DIRNAME and FQUALIFY functions being used.
- DELIMPOS(_dir, ./) <> 1 tests if the directory name in _dir starts with a dot or slash, and thus is a POSIX named directory. The FSYNTAX function could have been used for this purpose too.
- An MPE name can be converted to a POSIX name easily:
- DIRNAME returns the directory portion, in POSIX syntax, of a filename, but does not qualify the name.
- FQUALIFY qualifies the name in _dir. Now, DIRNAME will return the absolute path of the name in _dir1, less the file portion of the name.
- BASENAME returns just the base (file) portion of the name in _dir. When appended to the result of DIRNAME(
) the result is a fully qualified, POSIX name.
- LISTFILE will search for just POSIX (HFS) named directories (seleq=[object=hfsdir]), and the TREE option tells LISTFILE to search recursively, following all sub-directories.
