curly brackets mean what in kdb+q?

[DJ]

I have inherited some kdb+ code and can’t understand it.
What do the curly brackets mean in kdb/q?

[John Dempster]

Curly brackets contain a function. e.g.
{x+1}
would be a function that adds one to it’s argument.

{[a] b:a*10; b}
In this function we have named the argument a
Created a variable b which is ten times a
and returned that vlue (Since it’s the last statement)

{} is only used to contain function bodies there is no other use in kdb.
