File Types Comparison

isCOBOL - Micro Focus COBOL - ACUCOBOL-GT - RM/COBOL

The table below shows the compatibility between isCOBOL and other COBOLs with regards to sequential, relative and indexed files.

A green background means full compatibility (no action required) while a yellow background means that a data migration is required and can be accomplished easily using compilers and utilities provided by Veryant and the other COBOL vendor.

A red background means that a conversion program must be written. Contact your Veryant representative to discuss professional services to help in these cases.

Requires conversion
Follow the procedure outlined below
Unsupported file format (rarely used)
Requires conversion
Follow the procedure outlined below
Indexed with fixed-length records Access to Vision files provided via a licensed copy of the ACUCOBOL-GT runcbl library Requires conversion
Use jutil -convert to convert these files to Veryant JISAM format
(The Micro Focus rebuild utility is required by JUTIL in order to faciliate the conversion)

Requires conversion
Convert to Veryant JISAM format with the following steps:
1) Create an empty JISAM file by running a program that opens for output the FD with isCOBOL
2) Unload data from the input file using the RM/COBOL recover2 utility
3) Run jutil -loadr2

Indexed with variable-length records

Procedure for converting variable-length record Binary Sequential or variable-length record Relative files to a supported Veryant format

Write a program to be compiled and executed with ACUCOBOL-GT, Micro Focus or RM/COBOL that does the following:
