Information from multiple CICS host applications is gathered and the information is displayed on a single display screen. The information includes graphics, reports, and monitoring information. The display screens that the user is presented with are in a format that correspond to the host display screens that are commonly employed in large data processing (DO) centers. A host based status array is used to minimize the overhead of the communications between the host and the PC. The IBM 3270-PC or other microprocessor with a host communications interface receives existing, summarized information and reduces the information to a complete, accurate picture of the multiple applications that enables the operator to have timely information and respond effectively in a complex DP environment. The alarm information is organized to effectively call the operator's attention to a key problem quickly and efficiently. Key alarm messages can be designated as voice messages which are automatically translated and output as synthesized voice alerts. Threshold conditions can be called to the operator's attention by specifying tolerances, that once exceeded, trigger an electronic tone of designated frequency and duration.
