This topic covers the implementation details of Tmc_2x3y_Fraction.

 

Scope: TypeDefinitions.pas; record. Prepared from the curated implementation supplied for this review on 2 October 2026.

 

Native split-date formatting for the two date numbers and separator. fmt2324, fmt3031 and fmtSEP delegate to TmcTextSettings; separator, skew and tracking fields are integers/strings in their stored units.

 

Initialize supplies separator / and default font settings. IsDefault controls empty typed-node export. Do not confuse Track2324/Track3031 with a universal tracking scale without the formatter’s unit definition.

XML identity and composition

 

Literal rec_type values emitted within these routines: Tmc_2x3y_Fraction. Nested values may belong to child wrappers rather than this owner itself; the attribute entries below give their exact locations.

 

Structures used directly by this XML implementation:

 

TmcTextSettings

 

Exact XML fields and attributes

 

The paths below start at this record or property node. A slash identifies a child element; @ identifies an attribute. Curly braces mark a variable index or expression, not literal XML text. Initial values describe initialization; they do not establish what an omitted individual element does. The Implementation toggle below contains the supplied routines for exact branch order and conversions.

 

strSEP

 

XML representation: The text of the strSEP element.

 

Initial value: “/” (Tmc_2x3y_Fraction.Initialize).

 

Reading: Reads the element into strSEP when the record node exists.

 

Writing: Stores strSEP when the record’s DoesSomething check succeeds.

 

SkewSep

 

XML representation: The text of the SkewSep element.

 

Initial value: 0 (Tmc_2x3y_Fraction.Initialize).

 

Reading: Reads the element into SkewSep when the record node exists.

 

Writing: Stores the text representation of SkewSep when the record’s DoesSomething check succeeds.

 

Track2324

 

XML representation: The text of the Track2324 element.

 

Initial value: 0 (Tmc_2x3y_Fraction.Initialize).

 

Reading: Reads the element into Track2324 when the record node exists.

 

Writing: Stores the text representation of Track2324 when the record’s DoesSomething check succeeds.

 

Track3031

 

XML representation: The text of the Track3031 element.

 

Initial value: 0 (Tmc_2x3y_Fraction.Initialize).

 

Reading: Reads the element into Track3031 when the record node exists.

 

Writing: Stores the text representation of Track3031 when the record’s DoesSomething check succeeds.

 

TrackSepLeft

 

XML representation: The text of the TrackSepLeft element.

 

Initial value: 0 (Tmc_2x3y_Fraction.Initialize).

 

Reading: Reads the element into TrackSepLeft when the record node exists.

 

Writing: Stores the text representation of TrackSepLeft when the record’s DoesSomething check succeeds.

 

TrackSepRight

 

XML representation: The text of the TrackSepRight element.

 

Initial value: 0 (Tmc_2x3y_Fraction.Initialize).

 

Reading: Reads the element into TrackSepRight when the record node exists.

 

Writing: Stores the text representation of TrackSepRight when the record’s DoesSomething check succeeds.

 

@rec_type

 

XML representation: The rec_type attribute.

 

Writing: Stores the literal text “Tmc_2x3y_Fraction” whenever the writer reaches this field.

 

Nested records and repeated elements

 

 

Initialization and reset values

 

Tmc_2x3y_Fraction.Initialize

 

 

This routine also calls fmt2324.Initialize; fmt3031.Initialize; fmtSEP.Initialize. See Implementation for their order and any conditional calls.

 

Tmc_2x3y_Fraction.ResetToDefaults

 

This routine also calls Initialize. See Implementation for their order and any conditional calls.

 

Storage declarations relevant to interpretation

 

These are in-memory member and property types, not a list of mandatory XML children. They retain array bounds, fixed buffers and selector types. The field reference above defines what is actually serialized.

 

 

Implementation details

 

The Implementation toggle contains only Tmc_2x3y_Fraction methods. Initializers and helpers belonging to other types are identified separately below. Shared XML-helper limitations are explained in Reading this reference.
