numpad [ option(s) ] [ input file ]The options are:

NUMPAD is not like most languages. In the input file, everything except letters are ignored. The program is not case sensitive, which means that it does not differentiate between upper and lower case letters. Each word in the input file is changed into a decimal value corresponding to the sum of the values of each letter in the word, according to this chart:
LETTER VALUE ------ ----- abc 2 def 3 ghi 4 jkl 5 mno 6 pqrs 7 tuv 8 wxyz 9 ____________________ | | | | | 1 | 2 | 3 | | abc | abc | def | |______|______|______| | | | | | 4 | 5 | 6 | | ghi | jkl | mno | |______|______|______| | | | | | 7 | 8 | 9 | | pqrs | tuv | wxyz | |______|______|______|The value of each letter corresponds to the number with that letter on a telephone keypad!
2. Word Values
After a word is given a value, it is interpreted to have a meaning based on that value. In the following chart, the value in the left column represents an instruction that is the first word in the "MEANING" column.
