Abbreviations for data types is very convenient for data entry to searches or resources.
1. Strong's data types can be recognised from an entry like <G234> or <H145>. An abbreviation for G/K numbers in resources is Greek GK #221 but <Greek GK #221> is interpreted as Strong's <G221> when used in a search.
<GreekGK 221> is interpreted as intended so variations should be allowed.
(The formal syntax is <GreekGK ~ Greek GK #221>).
2. When used in DBL Greek resource GreekGK 221 has menu items for Greek GK #221 and Strong's Greek #221.
This ambiguity needs to be resolved.
