Has anyone been using this program?

Im currently using the option modebooks which combines affix(1word)+suffix(1word)

Is there a way to use it by say affix or suffix using 6+words

Does anyone know what this command does in the script?

//Maximum length of each Prime word (+1 because first byte contains word length)
#define MAX_LEN_WORD_PRIME 20

//Maximum length of each Affix word (+1 because first byte contains word length)
#define MAX_LEN_WORD_AFFIX 4

Thanks for any support and advice
