1 SIX
 A simple extraction utility, used to list specific lines from files.

              SIX  :==  $_DRC3:[GREC.E]6.EXE

 Format:
              $ SIX  input-file[,file...]  [range,...]

2 parameters
 Input-file

   If the file name contains wildcards, or more than one filename is
   specified, then the output from each file will be preceeded by
   a row of asterisks and the name of that file.

 Range

   You may specify one or more ranges, separated by commas, after
   the file name.  See GHELP RANGE for range-specification syntax.
   These are in addition to, not instead of, any other ranges selected.

   Negative line numbers counted backwards from the last line in the file
   (the last line is number 0).
2 qualifiers
/HEAD
    /HEAD=n

 This qualifier is used to list out the first n lines in the file.
 This is equivalent to /RANGE=(:n)
/OUTPUT
   /OUTPUT=file

 This qualifier redirects output to a new file.
/RANGE
   /RANGE=(range,...)

 This allows you to specify which lines are to be listed.
 Those given are in addition to, not instead of, any other ranges selected.
/TAIL
   /TAIL=n

 This qualifier is used to list out the last n lines in the file.
 This is equivalent to /RANGE=(-m:) where m equals n - 1.
