This version of
Data File Editor
has the following restrictions:
- This version of
Data File Editor should only be used with the version of Visual COBOL or Enterprise Developer that it was installed with. The executable is
not compatible with previous versions of either of these development products.
- Editing files is not supported if your environment contains any form of filename manipulation; for example, the DATAFILE and
FILESUFFIX options within an
extfh.cfg file, or the setting of the COBDATA environment variable. To work around this restriction, open
Data File Editor from the Windows menu, ensuring no such filename manipulation variables are set at a system level.
- The only supported UNIX platforms are SUSE, Red Hat, Solaris SPARC, and AIX.
- There is no support for Unicode files.
- There is no file conversion functionality; use the DFCONV command line utility if you require this functionality.
- Earlier releases of this product used structure files with a
.dfs extension. These files were a different structure to the conventional structure (.str) files. In this release and beyond, we have reverted back to the conventional
.str files. If you use
.dfs structure files, you must recreate those structure files.
- There is no support for the following types of data file:
- ACUCOBOL-GT (Vision)
- National data items are not supported in record or segment layouts.
- The editor is unable to display the Euro character (€) correctly. If you open a file that contains the character, it will
be preserved after the file is closed as long as you do not edit it directly.
- Line sequential files cannot contain binary characters. The INSERTNULL configuration option, which is ON by default, is ignored.
- Line sequential file and relative files both use 0D0A as a record terminator on Windows, and 0A as a record terminator on
UNIX. The LSRECDELIM and RELRECDELIM configuration options are ignored.
You cannot insert or append records for sequential ESDS files.
Note: The normal file system only allows you to append records to the end of this type of file.
You cannot delete or resize records for ESDS files.
Note: The normal file system does not allow you to delete or resize records for this type of file either.
- When using compressed files through Fileshare, user-defined compression routine executables must reside on both the client
and the server machine (and be on the PATH) in order to effectively edit the data file.
- When editing records, Insert mode does not work when using a layout; you can only edit in Overwrite mode.
- A limitation of the Windows clipboard means that when cutting or copying text from the editor, if the selection contains 0x00,
any text after this character is truncated when pasted from the clipboard.
