Data access
• Fixed length sequential and relative files coming from COBOL-IT are fully supported by isCOBOL.
• Indexed files from COBOL-IT are either VBIsam or DIsam. isCOBOL doesn’t support these file formats so indexed files must be converted either to c-tree or JIsam with the following steps:
a. unload file data to a raw binary file with COBOL-IT tools
b. create an empty c-tree or JIsam indexed file by running a program that opens the file for output with isCOBOL
c. load data from the raw binary file into the empty indexed file with
ctutil or
JUTIL.
