Summary: ISAM files created under Versions 1.x of COBOL must be rebuilt in order to use them in Versions 2.x. The following are two ways to rebuild files: 1. Use the REBUILD utility. 2. Write a program Version 1.x COBOL program to READ the Version 1.x ISAM file and WRITE the data to a Version 1.x Line Sequential file. Then, write a Version 2.x COBOL program to READ the Version 1.x Line Sequential file and WRITE a Version 2.x ISAM file.
