5.2.6  Splitting strings into lists of tokens

The split command splits a string into a sequence of substrings with respect to a given separator.

See Section 9.1.9 for other uses of split.

• split takes two arguments:
  • str, a string.
  • sep, a string specifying the separator.
• split(str,sep) returns a list of substrings [s₁,s₂,…,s_n] of str such that s1+sep+s2+sep+..+sn returns str.
• To trim the returned substrings, you can enter the command apply(trim,res) provided that res holds the return value of split (see Section 5.2.5).
