From a
Visual COBOL command prompt, you can invoke the Data File Editor using the following syntax:
mfdatatools [file-type] [file-name] [/org org-type] [/reclen record-length] [/charset char-set]
- file-type
- Can be one of
- /data
- Use this type if you are opening an existing data file. You must specify this if you are also supplying any of the additional
data file attributes (organization, record length and character set). This option may be omitted if you are not supplying
additional data file attributes.
- /create_str
- Use this type to create a new record layout file (.str file).
- file-name
- The (path name and) file name of the file to open or create. If you are opening a data file or record layout file, you must
specify a valid
.dat or
.str file. If you are creating a record layout file, you must specify the (path name and) file name of a valid debug information
file (.idy file).
- /org
org-type
- The organization of the data file being opened.
org-type can be one of:
| option |
description |
| seq |
sequential |
| lseq |
line sequential |
| rel |
relative |
Note: For data file types that contain a file header (for example, indexed), you do not need to specify this parameter.
- If you specify this parameter, you must also specify the
/data file-type.
- /reclen
record-length
- The record length. (This is the maximum record length if the organization is relative.)
Note: For data file types that contain a file header (for example, indexed), you do not need to specify this parameter.
- If you specify this parameter, you must also specify the
/data file-type.
- /charset
char-set
- The character set of the data within the file.
char-set can be either
ansi or
ebcdic.
Note: For data file types that contain a file header (for example, indexed), you do not need to specify this parameter.
- If you specify this parameter, you must also specify the
/data file-type.
Comments:
If you run
mfdatatools without any additional parameters, the IDE is displayed without any file opened.
