HP COBOL programs execute in a virtual memory environment.  Therefore,
  programs need not manage physical memory by overlaying Procedure
  Division code.

  In HP COBOL, segmentation controls the assignment of Procedure
  Division sections to fixed or independent segments.  The optional
  segment-number in the section header specifies the type of segment.

  Format -

   section-name SECTION [ segment-number ] .
