A function is niladic if it does not accept any arguments. For example:
∇ z←dealcard
[1] z←? 52
∇
This function would return a random number in the range 1 - 52, but it would not accept any argument. Such a function might be useful in the case of dealing a card in a game since the number of cards is always the same.
Some System functions are niladic in that they return a value, but you do not present them an argument. The ⎕TS function returns the current time stamp, that is, the current date and time, but you cannot give it a date or time in order to, for example, change the date or time.
