same as find except that as long as the file is 'NOT FOUND',
isafile calls
DIALOG_PICKFILE, to ask the user to select a file.
isafile
Input/Output
result = isafile([filein], FILENAME=FILENAME, IODIRECTORY=IODIRECTORY, NEW=NEW, RECURSIVE=RECURSIVE, ONLYPRO=ONLYPRO, ONLYNC=ONLYNC, _EXTRA=_EXTRA)
Return value
the filename with its path
Parameters
filein
in
optional
a proposed name. If neither filein input parameter or filename keyword are
defined, we ask the user to choose a file.
Keywords
FILENAME
a proposed filename.
IODIRECTORY
a directory where we look for the file. this
keyword is taken into account only if the dirname
of filein or filename is '.'
NEW
to specify that filename is a new file and that we should check only its
path
RECURSIVE
performs recursive searching of directory hierarchies.
In a recursive search, find looks recursively for any and all
subdirectories in the file hierarchy rooted at the IODIRECTORY argument.
ONLYPRO
force to look only at file ending with .pro
ONLYNC
force to look only at file ending with .nc
_EXTRA
Used to pass keywords to find,
FILE_SEARCH and
DIALOG_PICKFILE
