Using the IMS Database Editor Command Line Utility

From a Visual COBOL command prompt, you can invoke the IMS Database Editor using the following syntax:

mfdatatools [file-type] [file-name] [/imslib imsgenpath] [/imsdat imsdatabasepath] [/acblib path]
file-type
Can be one of
/create_slf
Use this type to create a segment layout file (.slf). If you specify this option, you must also specify the /imslib option.
/dbd dbdname
Use this type to open a database from a DBD file. If you specify this option, you must also specify the /imslib and /imsdat options.
/psb psbname
Use this type to open a database from a PSB file. If you specify this option, you must specify the file name without the file extension, also you must specify the /imslib and /imsdat options.
file-name
The (path name) and file name of the debug information file (.idy) file. Specify this option only when creating a segment layout file (option /create_slf).
/imslib imsgenpath
The location of DBDGEN2.DAT, DBDGEN2F.DAT and PSBGEN3.DAT files. This is the equivalent of setting the ES_IMSDAT environment variable; if this variable is already set, you do not need to specify this parameter.
/imsdat imsdatabasepath
The location of the IMS DB files. This is the equivalent of setting the ES_IMSLIB environment variable; if this variable is already set, you do not need to specify this parameter.
/acblib path
The location of IMS ACB files. This is the equivalent of setting the ES_ACBLIB environment variable; if this variable is already set, you do not need to specify this parameter.
If this parameter is omitted, the path name specified for /imslib is used.

Comments:

If you run mfdatatools without any additional parameters, the IDE is displayed without any file opened.
