Converting Indexed Files

The vutil convert function is accessed on the Convert tab. The convert function allows you to convert an indexed data file created by C-ISAM or RM/COBOL-85 into a Vision indexed file. This is useful when you are moving data from a C-ISAM or RM/COBOL-85 application to an ACUCOBOL-GT application.

Note: Because the Vision file replaces the original C-ISAM or RM/COBOL-85 file, be sure that you have a backup copy of the original file.

The convert function has a number of limitations. It does not convert files that have:

Record or block sizes greater than 32 KB
More than 120 keys
Individual keys larger than 250 bytes
Non-ASCII characters or collating sequence (RM/COBOL-85)
Split keys (RM/COBOL-85)
A single key with more than 16 segments (Vision Version 4) or more than six segments (Vision Version 3) (C-ISAM)
A primary key that allows duplicates (C-ISAM)

Note: When converting files you must have plenty of available disk space to accommodate the differences in file size between the original file type and the converted file type. You must also allow vutil space to copy the file during the conversion process.
