Beginner Question

Hello all!

I was fooling around with some simple concepts and cannot get the following to
print out correctly (in the Dos window, I'm using Winxp).

with trace
trace(1)
atom a
sequence Var1, Var2, Var3

Var1 = "apple"

Var2 = "orange"

Var3 = "File"

printf(1, "Var1 equals: %s\n", {Var1})
printf(1, "Var2 equals: %s\n", {Var2})

Var3 = append(Var3, Var1)

printf(1, "Var3 after append equals: %s\n", Var3)
printf(1, "Var31 after append equals: %s\n", Var3[1])
printf(1, "Var32 after append equals: %s\n", Var3[2])
Var3 = prepend(Var3, Var2)

printf(1, "Var3 after prepend equals: %s\n", Var3)

a=getc(0)
trace(0)

This 1st printf's work fine, the next one where Var3 is printed out after the
append gives "F", the 1st letter of "File".  The next printf gives "F" again,
the next gives "i", the last "orange".

When running trace, the variables are assigned correctly, i.e. Var3 gives
"appleFile" then "appleFileorange".  What am I doing wrong?

Also, in the Euphoria Reference Manual, under printf, it states when using
printf to watch out for:
printf(1, "%s", name) and to use {name} instead.

However, this always gives a error when I tried it on Var3, taking these out,
the
program ran fine, well, almost fine, other then it's not outputting correctly!!

Any help would be appreciated!!
Thanks
