Section 12: Source_Format

 Each Fortran line has the following four fields:

   Statement label field           Columns 1-5
   Continuation indicator field    Column 6
   Statement field                 Columns 7-72 (if you specify 
                                     the EXTEND_SOURCE compiler
                                     option or OPTIONS/EXTEND_SOURCE, 
                                     statements extend to column 132)
   Sequence number field           Columns 73-80

 There are two ways to code a Fortran line:  standard formatting and
 tab formatting.  You may prefer to use the standard formatting when
 program portability to other systems is necessary.  The tab
 formatting method is convenient when you are entering lines at a
 terminal with a text editor.
