digraph

In some programming languages, a digraph is two common keyboard characters used together that represent one symbol. For example, (* and *) have represented the curly braces { and }. A trigraph uses three characters such as ??- for a tilde ~. Digraphs and trigraphs are methods for ensuring symbols can be entered into source code from an abbreviated keyboard that has fewer keys than a full-size unit.

The results of his analysis of the use of double consonants in various phonological environments in his opinion show that vowel quantity is the main factor that determines the use of <CC> digraphs.
One of those who look for the results of OSL to show that <CC> digraphs mark short vowels is Phillips (1992).
In his discussion of the possible functions of <CC> digraphs in MS Junius 1, Fulk (1996) puts forward a few very convincing counter-arguments to Phillips' (1992) hypothesis.
