/BLOCKS[=(option,...)]
Similar to DUMP/BLOCKS; extracts blocks from the input file(s) without
interpreting their record structure.
Up to two of the following options may be specified; if more than one
is used, separate them with a comma and enclose the list in parentheses.
START=m starting block number; the first block in the file is 1.
A negative value specifies a number of blocks relative
to the end of the file: -1 is the last block, -2 is the
one before that, etc.
END=n ending block number; the last block of the file is
considered to be block number -1.
COUNT=k number of blocks to extract. If START is specified, END
is derived by adding COUNT-1 to it; if END is specified,
START is derived by subracting COUNT-1 from it; if neither
is specified, START is 1 and END is set to COUNT.
Incompatable with /RECORDS, /HEAD, and /TAIL. Also incompatable
with /COLUMNS, /EXPAND_TABS, /TRANSLATE, and /VFC_HEADER.
