Common Block Variables

The common block provides access to system information at various levels within an application.

Developers must include the common block within their routines and must ensure that all routines that include the common block are re-compiled for new versions of the system.

 All subroutines should resemble the following skeleton code:

SUB subname(html) 
    *--- include the common block 
    INCLUDE sysbp syscommon 
    *--- user defined code follows 
    * set HTML where appropriate 
    *--- always return when code completes
