File Descriptors

Tools can output files that are to be interpreted as value tables. The contents of these value tables must be described in the AWM model. See File Descriptor in the Data Model Details chapter, for more information.

Files of this kind are returned to the following places in the example AWM model shown below:

Expansion of tree elements (MVS_FD_ELE_MVS_DataSetList, MVS_FD_ELE_Memberlist, MVS_FD_ELE_ViewFilter, MVS_FD_ELE_ViewStaticEntry)
Return of element lists in the table view ((MVS_FD_ELE_MVS_DataSetList, MVS_FD_ELE_Memberlist, MVS_FD_MemberSearchresult)

The relationships of the file descriptors to properties are shown in the figure below:

MVS PRoject Sample Application File Descriptors

The table below describes a few important file descriptor attributes:

File Descriptor	Attribute	Description
MVS_FD_ELE_MVS_DataSetList MVS_FD_ELE_Memberlist	Type = Input Stream Structure = Table Delimiter = /%/$/	The data set and member list are provided by MVS function package tools as input streams. The values are separated by /%/$/
MVS_FD_MVS_SequentialFile	Type = MVS_Seq Structure = Unstructured Name Physical = &MVS_PROP_ELE_DSName.	A file descriptor used to edit a sequential file. The "Name Physical" references the property which contains the relevant data set name.
MVS_FD_MVS_Member	Type = MVS_PO_Member Structure = Unstructured Name Physical = &MVS_PROP_ELE_DSName.(&MVS_PROP_ELE_MemberName.)	A file descriptor used to edit a PO member. The "Name Physical" references the property which contains the relevant data set name including the member name.
