kdb while loop

[Matt Bell]

Hi,

Is it possible to write a while loop in kdb?

Or what about other loops, does kdb support for loops, do while loops?

How can I control running a process a certain number of times?

Yes it is possible to do that. You can look it up at http://code.kx.com/wiki/Reference/while

I can give you an example:

cumsum:{[n]
a:0;
while [not n = 0;
a:a+n;
n:n-1;
];
:a
}

I believe it is self explanatry what happens.

I hope this answers your question.

Regards,

Chris
