}

An abbreviation id is a fixed-width field that occurs at the start of abbreviated data records and inside block definitions.

Bitstream reserves 4 special abbreviation IDs for its own bookkeeping.

Variants

EndBlock = 0

Marks the end of the current block.

EnterSubBlock = 1

Marks the beginning of a new block.

DefineAbbreviation = 2

Marks the definition of a new abbreviation.

UnabbreviatedRecord = 3

Marks the definition of a new unabbreviated record.
