1.07 1.10 1.12 MS-DOS

Question: How can I use data files created using previous versions of MS-COBOL to convert to 1.12-style data files?

Response: All ISAM files (“ORGANIZATION IS INDEXED”), created or modified by versions of COBOL prior to Version 1.10 must be rebuilt with Version 1.21+ of the REBUILD utility. When converting to Version 1.12 from previous versions, all programs must be recompiled (this is true of all COBOL product upgrades). Programs may not work properly when compiled with versions previous to 1.12 and linked with Version 1.12 libraries.
