Control elements

Elements under the Control category are the items that are used as components of the group types under the Control category.

For example, elements that appear in the ISA, ISB, and TA1 segments are defined here. Expand the Element category to view an alphabetical list of the elements.

Most of the definitions of the Element subtypes conform to the interchange standard, not the version standard. The main difference is the interpretation of the N0 notation that is used in X12. The N0 notation in the interchange standard refers to an unsigned integer. In the version standard, the N0 notation refers to an integer, possibly preceded by a negative sign.

For example, the InterchangeCtrl# and #InclFunct'lGroups elements are part of the interchange standard and are defined in the schema as an unsigned integer. The GroupCtrl# Element, however, appears as part of a version standard, and is therefore defined as an ANSI implicit decimal with zero decimal places.
