Message-writer routine

HCL Workload Automation for Z passes the address of an HCL Workload Automation for Z communication area (the MCA block) to each subtask it attaches. The MCA contains data shared by subtasks and the addresses of common subroutines.

One of these common routines is the message-writer routine. All HCL Workload Automation for Z subtasks use this routine to issue messages to the operator and to the HCL Workload Automation for Z message-log file.
