Split variable into multiple columns

[SASPhile]

How to split raw_variable into multiple variables of lengths 20 and not to break a word.

i.e in below example "acerbic soluable dio" is not the way to split it. dioxide;zinc goes to other variable and so on.

raw_variable
acerbic soluable dioxide;zinc titanium

Raw_var1                               Raw_Var2                  Raw_var3
acerbic soluable                     dioxide;zinc                 titanium

Thanks for the help!

It would be simpler to split up your string into single words. One could then still concatenate the words back into strings of up to 20 characters.

If re-concatenating words: Do you really need the semicolon in Raw_Var2 or could we just add a blank here?

What should happen if a single word has more than 20 characters?

 In fact the delimiters are semi-colons. So they are required. 

acerbic;soluable;carbon dioxide
