การพัฒนาโปรแกรมให้ไมโครคอมพิวเตอร์และเมนเฟรมร่วมกันใช้ ซียูไรเตอร์ / ลดารัตน์ ผ่องอุไร = Development of programs for coordinated use of CU Writer on microcomputers and mainframes / Ladarat Pongurai
In many offices, much of the work done on computer was related to word processing and the management of documents. Significant space was taken up on disks of PCs, creating problems with the efficient and secure storage, archiving and retrieval of these data. Therefore, the development of software which allows word processing programs, and CU-Writer in particular, to be used in a PC/mainframe environment should be a useful step in solving these problems. A set of programs which resided on the PC initiated the upload or receive the download of files and sent a command to the 3270 emulation software instructing it to establish a connection between PC and mainframe. On the mainframe a set of programs running under CICS which waited for data from the PC and store it in the CICS temporary storage area. The data was transferred from there to a VSAM file. On another hand, these programs would read data from a VSAM file and store it in CICS temporary storage, then waited for a request from the PC to download. Word processing users on the PC could also request the deletion of documents stored on the mainframe. The development of software which allowed transparent CU-Writer on a PC while providing for centralized storage and management of documents on a mainframe, represents an effective solution to a growing problems. The two systems cooperated with each other, the PC provided a user-friendly interface and rapid interactive response time while the mainframe environment provides for ample and secure file management, dependable backups and coordinated control of the documents.
