For the lecture Enterprise Mainframe Computing a project was developed in collaboration. The project named “ZBANK” is an application written in COBOL and uses CICS as a transaction monitor, BMS as a user interface and a key-sequenced VSAM for data storage. In this document, we summarize the program code and the work done.

Different screens realized with BMS, all the communication is done in
CICS. Data is stored throughout different sessions in a key-sequenced VSAM file
