// Declension for special cases
// Usage syntax: {lookup: TEXT; FILE_NO_EXT; INDEX}
// TEXT is the key to access a row.
// FILE_NO_EXT is the file in which TEXT should be looked up. Omit the extension.
// INDEX determines the column to be used. Can be omitted if you need index 1.
// For example, {lookup: {0}; decline_other; 2} looks up 2_DAT.
