Ü   BEGSR (Beginning of Subroutine)

   

§  The op-code represents beginning of a subroutine placed in factor-1.

§  If factor-1 entry is *PSSR then this subroutine will handle all program exceptions/errors. Only one subroutine can be defined with *PSSR.

§  If factor-1 entry is *INZSR, it represents the initialization of the program and will be executed only once when the program starts. Only one subroutine can be defined with *INZSR.
