netCONVERT is designed to perform data file conversions between
Mainframe and UNIX file formats. A cross-platform solution, netCONVERT
runs under the MVS, VM, and a number of UNIX operating systems.
netCONVERT accepts data in one format and converts it to another.
The conversion may be any of the following
- one mainframe format to another
- mainframe format to workstation/desktop format
- workstation/desktop format to mainframe format
- one workstation/desktop format to another
netCONVERT also includes support for converting date fields from
two-digit format to three- or four-digit format, according to the
methodology adopted for Year 2000 remediation projects. Bi-directional
support for date conversions is supported, allowing bridging between
compliant and non-compliant applications as well as on-demand conversion
of archival data.
netCONVERT uses the COBOL File Description as the basis for data
mapping. If a COBOL FD exists for an input file, netCONVERT can
use that file for the record map. If a COBOL FD does not exist,
the options for defining the data mapping include
- using the
syntax of the filter program
- converting other types of data mappings to a COBOL FD
For date conversions, the COBOL FD is required since the date
conversion directives are specified as comments in the FD.
Regardless of the input or output source, you may specify record
length, blocksize, and record format. Mainframe record formats supported
Both the input and output sources may also be VSAM files, for which
you may specify the record organization as
- Fixed: F, FB, FBS
- Variable: V, VB, VBS
Workstation/desktop record formats supported include
- KS - key sequential
- ES - entry sequential
- RR - relative record
- Segmented (variable, but with a segment byte as in ANSI standard)
- Text (line-feed delimited)
- NT (like Text, but carriage-return/line-feed delimited)
- MFCOBOL (Micro Focus COBOL special variable format)
- CSV (comma-separated values)
Input may be from disk files, tape files, or other sources piped
to stdin. Output may be directed to disk, tape, or piped to other
sources through stdout.
Tape I/O includes support for both IBM and ANSI standard labelled
tapes as well as for unlabelled tapes. You may specify a volume
id, device name and file position for both input and output. For
output, you may also specify the file disposition and expiration
For conversions between platform types, netCONVERT includes a
standard ASCII/EBCDIC translation table that produces reversible
results. You may also define your own translation tables for data
or applications where the standard table does not achieve the desired
netCONVERT is designed for portability so that it can be executed
on virtually any platform in your network. The kernel is written
in ANSI Standard C.
netCONVERT includes several components:
The filter program is provided for all environments.
- filter program to access and translate data
- utility to automatically generate a new COBOL FD to match data
files in which date fields have been expanded
- a test data generator utility which will build and write data
files corresponding to any file description
The filter program may also be used in conjunction with Micro
Focus COBOL two-way pipes to allow a COBOL program to use the output
of the conversion process directly.
The FD conversion utility creates an expanded-date-compliant FD
from the original, in which date conversion directives were specified.
The output FD also has the date mappings reversed (to perform date
field contraction) as part of the support for bi-directional date
netCONVERT is available for all the following computing environments:
- IBM mainframe: VM, MVS, OS/390
- UNIX workstation: HP/9000, IBM RS/6000, Sun Solaris
