cencol, `%:`, %cncl

Slam, one argument

%: is a synthetic rune that that pulls $ from the door p with its sample set to q. %: in the most common case simply slams p with q, similar to a function call with one argument. Unlike its close relative %-, %: is designed for gates who take a single value as their sample.

Examples

/~zod/try=> %:(dec 42)
41

Here we use %: in its most straightforward form, to call an arm that takes one argument.

/~zod/try=> %:  dec
              %+  add  2
            %+  mul  2  20
41

Here we call ++dec with the sum of 2 and the product of 2 and 20 using %:. As you can see, %: is most useful for code organization, when you need to compute intermediate products for your final result
