[SOLVED] Does not give all solutions

[JamesWilliams]

To Didier Lachieze,

In CAS, I typed in the line exactly as you did, namely,

solve(cos(x) = 1/4)|(x>0 AND x<2*π)

and got the generic HP Prime error with the red circle and white X. Can you please tell me precisely how you entered this? In particular, what key did you press to enter the vertical bar? There is nothing in the description of solve in the user guide (p. 366) about this idea of adding a vertical bar followed by conditions. Where can I find more information about it?
