Dear Sir or Madam,

My name is Kuroki and I have a qusetion about title.
Can I call other protocol within a protocol?
For example this protocol image...

Read data.txt Component
->
Read other protocol Component
->
HTML Table Viewer

data.txt has been written
1
2
3
4
5

and result is
Text
2
4
6
8
10

and other protocol's image is...
No-op Component
->
Basic Math Component(Operatino is *)
->
No-op Component

Is it possible to operate this kind of image?

I look forward to hearing from you soon.
Yours sincerely,

Taro Kuroki
