x = "y" y = 5 ? x && shows the text, "y" ? evaluate(x) && Shows the valua of variable y - that is, 5.I find this very useful, for example, to create my own generic lookup function. The name of the field whose value must be returned after a SEEK(), are passed as one of the parameters. Instead of a single field, I can also use a more complicated expression, for example, concatenate two fields.
