 2.8 Configuring listing output: '--listing'
 ===========================================
 
 The listing feature of the assembler can be enabled via the command-line
 switch '-a' (Seea).  This feature combines the input source file(s)
 with a hex dump of the corresponding locations in the output object
 file, and displays them as a listing file.  The format of this listing
 can be controlled by directives inside the assembler source (i.e.,
DONTPRINTYET  '.list' (SeeList), '.title' (SeeTitle), '.sbttl' (*noteDONTPRINTYET  '.list' (SeeList), '.title' (SeeTitle), '.sbttl' (See
 Sbttl), '.psize' (SeePsize), and '.eject' (SeeEject) and
 also by the following switches:
 
 '--listing-lhs-width='number''
      Sets the maximum width, in words, of the first line of the hex byte
      dump.  This dump appears on the left hand side of the listing
      output.
 
 '--listing-lhs-width2='number''
      Sets the maximum width, in words, of any further lines of the hex
      byte dump for a given input source line.  If this value is not
      specified, it defaults to being the same as the value specified for
      '--listing-lhs-width'.  If neither switch is used the default is to
      one.
 
 '--listing-rhs-width='number''
      Sets the maximum width, in characters, of the source line that is
      displayed alongside the hex dump.  The default value for this
      parameter is 100.  The source line is displayed on the right hand
      side of the listing output.
 
 '--listing-cont-lines='number''
      Sets the maximum number of continuation lines of hex dump that will
      be displayed for a given single line of source input.  The default
      value is 4.
