I've just tried out the following script with input port in0 and
output ports out0 and out1.

File f0 = new File(in0);

if (f0.exists()) {
        out0 = "input port true";
} else {
        out0 = "input port false";
}

File f1 = new File("C:/Users/alanrw");
if (f1.exists()) {
        out1 = "string specified true";
}
else {
        out1 = "string specified false";
}

and both out1 and out2 generate the "true" values.

Paolo, can you try that (with a different string value) and see what
you get?
