HELP SECTION

PRTLEV
Type:  Adverb    (Scalar)
Use:   To limit the amount of information displayed by programs.  For
       example, PRTLEV = 0 instructs PRTTP to print only IMHEADER-like
       summaries of each FITS file.  With PRTLEV = 1, PRTTP also prints
       all FITS header card images except History cards and, with PRTLEV
       = 2, even the (probably numerous) History cards are printed.
