Hi Thomas,
no it doesn't return a sequence.
>From the manual:-
find
Syntax: i =3D find(x, s) =20
Description: Find x as an element of s. If successful, return the =
index of the first element of s that matches. If unsuccessful return 0. =
Note the key phrase in the manual "index of the first element".
To find all occurrences try this...
sequence result, word
integer x
result =3D {}
word =3D "experience"
for i =3D 1 to length(word) do
x =3D find('e', word)
if x then
result &=3D x
end if
end for
? result -- Should display {1,4,7,10}

Subject: Find what?
Hi evr'yone
I was wondering about find(). What if there are 2 of the same =
characters in a sequence? Like this:
sequence word
word=3D"beet"
atom findit
findit=3Dfind("e", word)
? findit
Does it give a [2..3] back?
-->Thanks
--->Thomas
