PURPOSE:To shorten the waiting time to enhance line availability, by executing plural command processing programs, which are inputted from a terminal, in parallel. CONSTITUTION:The command management program CMP main routine starts a command processing program corresponding to the inputted command by the ATTACH macro instruction and requests the input to the terminal user by XPUT GET macro instruction and waits the occurrence of a determined phenomenon by the WAIT macro instruction. When the command processing program started by the ATTACH macro instruction terminates normally, the control is returned to the CMP main routine by the RETURN macro instruction. When the input from the terminal user is completed, the completion of the input is reported by the POST command; and when the terminal user issues the attention interruption, the CMP attention exit routine is executed, and the control is transferred to the CMP main routine after execution. |
