3.3 File Utilities-vutil
On MS-DOS, OS/2, Windows, 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 full name of this 32-bit
utility is "vutil32", but throughout this discussion, we refer to it 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, change maximum record size, 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. The functions are designed to allow you to specify all possible task
parameters up front, so that the utility can run unattended or with a minimum of user
interaction. Each function is discussed below.
