3.3 File Utilities-vutil

On MS-DOS and UNIX systems, ACUCOBOL-GT uses the Vision indexed file system to manage its indexed data files. For these systems, ACUCOBOL-GT comes with an indexed file utility program called vutil that contains several useful functions. (The 16-bit version of vutil is called vutil16, and the 32-bit version is called vutil32. Throughout this discussion, we refer to the utility simply as vutil.) This section describes this program.

Note: Other file system interfaces have their own file utility packages. On VMS systems, for example, ACUCOBOL-GT uses the RMS file system that is intrinsic to VMS, and the vutil utility is not supplied. VMS-specific programs such as ANALYZE/RMS and CONVERT can be used to accomplish the same functions. See the manual for your specific file utility package for details on its use.

Vutil provides several functions in one package. It can be used to examine files, extract data records and rebuild corrupted indexes. Each of these functions is indicated by an initial keyword on the command line (preceded by a hyphen). This keyword may be abbreviated to its first letter. Each function is discussed below.
