"file Mask" uses MS-DOS file names and/or wild cards to control which files
you choose to view in the current directory.  Some ways to specify a mask
are shown below.

A mask of "*.ns" is the default and displays all files in the current
directory with a file name extension of "ns".  Upon starting up, NSChart
assumes that all NSPDL text files have this file naming convention, though
you are free to adopt any file naming convention you prefer.

A mask of "*.*" displays all directory entries, whereas a mask of only one
asterisk displays only those files with no extension.

A mask of "b*.*" displays all file names beginning with the letter "b",
whereas a mask of "b*" displays only those file names beginning with "b"
but with no extension as part of the file name.

A mask of "*.inc" displays only those file names with extension "inc".

A mask of "???" displays only 3-letter file names with no extension.
