        There is confusion on star type 0.  Changed:
        STARPL   Will plot a symbol for star type 0 if it does not
                 plot a label string.  Plots symbols for all positive
                 star types and plots no symbol for all negative star
                 types.
        STARS    Changed to set star type 0 to -1 if there is a label
                 string or +1 if there is not (also help file)
        GSTAR    Changed to limit FACTOR to 1 - 24, fixed help file to
                 list the current types.
        MF2ST    Changed to limit types to 1-24 and do the scaling in
                 the range.  Updated help file.
        STFND    Changed to limit star type to range 1-24 and changed
                 the CPARM(10) parameter to make the user really
                 request pixel coordinates (non-standard for ST files)
                 Updated the help file for these.
        Moved nowhere.

Will appear tomorrow.  The fix I made for you caused some problems
with other tasks that did stars one way or another.  STARS will make
type 0 into -1 if there is a string and +1 if not.

Cheers,
