func/addr write, [name] <, write, [name] ... >

Loads addresses of function objects into the named registers. The arguments are grouped in pairs of write and read.

write	Register to store the next pointer in. The pointer will be determined from the next name argument.
name	Name of function to lookup, supplied as a text string. This pointer will be stored in the register named in the previous write argument.

Function objects are located by searching the following in order:

local context
	Functions anchored underneath the current executing object.
module root
	Functions anchored to the module root.
.prose.code.sys
	System functions with global scope.

A runtime error is generated if the named function cannot be located.

func/addr P0, [main]
	Loads the address of the main function into the register P0.
func/addr PUSH, P0, PUSH, P1
	Pushes the addresses of the functions identified in registers P0 and P1 to the program stack.
