Obviously there is something about Euphoria that I don't
understand. Below is a small test program that writes data
to a disk file. Please explain what is wrong.

sequence s
atom fn
constant NAME = 1, AGE = 2, WAGE = 3

fn = open("TEST.DAT","w")

s = {"Sue Smith",32,22.50}
? s
printf(1,"Name: %s \n", {s[NAME]})
printf(1,"Age: %d  \n", s[AGE])
printf(1,"Wage: %4.2f \n", s[WAGE])

-- puts(fn,s) won't work "sequence found inside character string"
-- so we puts it one "field" at a time:

for i = 1 to length(s) do puts(fn,s[i])
end for
close(fn)

fn = open("TEST.DAT","r")
s = gets(fn)
close(fn)

? s
printf(1,"Name: %s \n", {s[NAME]})
printf(1,"Age: %d  \n", s[AGE])
printf(1,"Wage: %4.2f \n", s[WAGE])
