When clicking on "Start of Block" link to see details for tag 16R it is referred to as a field:

Solution

  • The field generally refers to the complete fields with its name and value. While the tag usually refers to the name of the field, including the number and optional letter option.

    However, in many places you will find that the terms are used interchangeably.
