Description

i3, i4, ..., in find(s1, s2, i1, i2)
A generator, find(s1, s2, i1, i2) generates the sequence of integer positions in s2 at which s1 occurs as a substring in s2[i1:i2], but fails if there is no such position.
 
Parameters
s1
the search string
s2
the string to search
i1
the starting position in s2
i2
the end position in s2
returns
a sequence of integer positions of s2 in s1
 
Defaults
s2
&subject
i1
&pos if s2 is defaulted, otherwise 1
i2
0
 
Errors
101 i1 or i2 not integer
103 s1 or s2 not string

Examples

Example 1 — Finding multiple instances in a sentence:
The map() function below, translates the sentence to lower case.
testStr := "The quick brown fox jumped over the lazy dog's back."
testStr := map(testStr)
every writes (testStr ? find("the"), " ")
returns:
