If you have allocated it with the Euphoria-function allocate, you could do 
it like this:

function resize_memblock(atom old_mem, integer old_size, integer new_size)
	atom new_mem
	if old_size = new_size then return old_mem end if
	new_mem = allocate(new_size)
	if old_size < new_size then
		mem_copy(new_mem, old_mem, old_size)
	else
		mem_copy(new_mem, old_mem, new_size)
	end if
	free(old_mem)
	return new_mem
end function

-- Using the function:

pointer = resize_memblock(pointer, size, size + 1000) -- adds 1000 bytes 
to the memory block
