Description

i3 many(c, s, i1, i2)
many() succeeds and produces the position in s after the longest initial sequence of characters in c with s[i1:i2]. It fails if s[i1] is not in c.
 
Parameters
c
character set of allowable characters.
s
subject string.
i1
start position in s.
i2
end position in s.
returns
tab position of last found character.
 
Defaults
s
&subject.
i1
&pos if s is defaulted, otherwise 1
i2
0
 
Errors
101 i1 or i2 not integer
103 s not string
104 c not cset

Examples

Example 1 — Splitting apart a Sentence:
In this example:
line = "This is the very first sentence in a paragraph"
line ? (firstWord := tab(many(&letters)) (theRest = tab(0))
will capture the first word of the sentence in one variable and the rest of the sentence in a second. The result of the above expression is:
firstWord := "This"
theRest := " is the very first sentence in a paragraph"
