COMMON

 The COMMON attribute specifies that storage for  a  variable  be
 allocated in an overlaid program section called a common block.


 Syntax:

    COMMON [[(identifier)]]

 The 'identifier' indicates the name of the common block.  It  is
 passed  in  uppercase  on  OpenVMS  systems.   If  you  omit the
 identifier, the name of the variable is used as the name of  the
 common block.

 This attribute allows you  to  share  variables  with  other  HP
 languages, such as FORTRAN.

 See the "HP Pascal Language Reference Manual" for  the  complete
 description of using the COMMON attribute.
