Help for TOASCII

      TOASCII is a VICAR program to convert part or all of a VICAR image file
into an ASCII table of values.  It is somewhat similar to the program LIST, but
has the following differences:
           1. Page headers, row headers, and column headers are not printed.
              The only headers printed are, in the case of multiple output
              bands, the band numbers for BSQ images and the line numbers for
              BIL or BIP images.
           2. The output is not split into strips, even if there are many 
              columns of output.  That is, TOASCII assumes an arbitrarily large
              screen or paper.
           3. The columns of pixels output need not be consecutive or even in
              order.  For example, the user may output samples 3, 7, 1, and 6
              - in that order.
           4. The user may provide a FORTRAN format statement to descibe the
              output format.
