field-name This entry identifies the field being accessed on the terminal
screen. If the field-descriptor is 0,0 (i.e., for an exact match), the field-name
must uniquely match text on the screen or must be a hyphen to indicate that
the field is at the current cursor position. When entering the field name, keep
in mind that the TRS process right-justifies all field names and removes all
extra white space. If the transaction fails, this field identifies the current
screen so the reset-action template can be executed.
If you enter "0,0" and a hyphen for the row, column and field-name entries,

specify a location, such as 24,8 for the location of the action specified by the
field-I/O entry.
