Error handling in interactive and procedure modes

LMS differentiates between the interactive mode and the procedure mode of execution.

• Interactive mode

  In interactive mode, following output of the error message, the prompt // appears, requesting entry of the next statement.

• Procedure mode

  LMS supports two error handling mechanisms in procedure mode. A spin-off mechanism and a statement return code mechanism. The setting of the PROPAGATE-STMT-RC operand in the /BEGIN-BLOCK command determines which of the two is effective.
