This course is designed to teach application developers to write COBOL programs to access VSAM files in Key Sequence via primary key and via alternate keys, to access ESDS and (optionally) RRDS VSAM files, and to write and update each type of VSAM file. The course presents the necessary logic for dynamic access and updating of data and contrasts that with sequential file access and update.
