i just wonder is it possible to make an alias or data manipulation in package
10 = 0 20 = 0 30 = 0 40 = 0
11 = 1 21 = 1 31 = 1 41 = 1
12 = 2 22 = 2 32 = 2 42 = 2
13 = 3 23 = 3 33 = 3 43 = 3
14 = 4 24 = 4 34 = 4 44 = 4
15 = 5 25 = 5 35 = 5 45 = 5
16 = 6 26 = 6 36 = 6 46 = 6
17 = 7 27 = 7 37 = 7 47 = 7
18 = 8 28 = 8 38 = 8 48 = 8
19 = 9 29 = 9 39 = 9 49 = 9
would it be hard to make such code?
thank for any info
