Level 2 Help for TOASCII

Name of the VICAR input file.

Name of the ASCII output file.  This file will have no VICAR labels.

The size parameter determines the portion of the input file to be converted
to ASCII data and output.  It is specified as  (SL,SS,NL,NS), where
	SL is the starting line 
	SS is the starting sample (column)
	NL is the number of lines to be output
	NS is the number of samples (pixels) in each line

The bands parameter determines the bands in the input file to be converted to
ASCII data and output.  It is specified as (SB,NB), where
	SB is the starting band
	NB is the number of bands to be output

The user may override the default print format by supplying a valid FORTRAN
FORMAT statement as the value of this parameter.  For example,
FORMAT="(9X,I5,3X,I7)" would yield columns as follows:

         #####   #######
         #####   #######
         #####   #######
         #####   #######
         #####   #######
         #####   #######
Note that parentheses enclosing the full format expression are required, with
quotes enclosing the parentheses.

COLUMNS is an alternate method (to the SIZE field) of describing which sample 
positions are to be output.  It is an explicit list of the sample positions to
be output.  For example, COLUMNS=(4,5,6) would yield the same result as SS=4,
NS=3.  The output columns need not be consecutive or sequential;
COLUMNS=(1,9,4) will output Sample 1 as Column 1, Sample 9 as Column 2, and
Sample 4 as Column 3.
