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,…,sn] 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).
