The following provides a description of each parameter:
Indicates the 1- to 8-character name to be associated with the field being defined. For more information about the system-defined TMC field names, see TMC Reference.
Important! A site-defined field must fit entirely inside a single system-defined TMC field.
Indicates a 1- to 8-character system-defined fieldname on which to base the offset.
Indicates the default system-defined fieldname on which to base the offset.
Specifies a relative displacement into the system-defined TMC field.
Specifies an absolute displacement, in decimal format, into the TMC record.
Note: You can still use this method of defining a field by specifying an absolute Record with the offset parameter; however, for future compatibility reasons, its continued use is strongly discouraged. Because some field locations in the TMC have changed, the possibility exists that an absolute offset may overlay the wrong data.
Is the edit code of the field. Any definition of the form CHARnn is valid where nn specifies the length of the field and is between 1 and 50, inclusive, as well as BIN1, BIN2, BIN4, HEX1, HEX2, DATE, and TIME.
Specifies site-defined field editing. The nth routine in the USEREDDF exit performs input and output editing of this field.
Specify a site-defined field type as USER1, USER2, and so on. (The actual input/output conversion and formatting for USERn field types are handled by the USEREDDF user exit.)
Specifies that this field can be modified by end users (USER) or cannot be modified by end users (NONUSER).
Specifies that this field is displayed as the last line on the long form of the LIST command (DISPLAY) or is not displayed to the end user (SUPPRESS).
USER | NONUSER and DISPLAY | SUPPRESS Interaction
The USER|NONUSER and DISPLAY|SUPPRESS parameters operate independently of each other. For example, by specifying NONUSER DISPLAY, the user can see the field but not modify it.
