57### `++ind:po`
59Parse suffix
61Produces the byte of the right-hand syllable `a`.
63#### Accepts
65`a` is an atom.
67#### Produces
69A `unit`.
71#### Source
73```hoon
74 ++ ind ~/ %ind
75 |= a=@tas
76 =+ b=0
77 |- ^- (unit @)
78 ?:(=(256 b) ~ ?:(=(a (tod b)) [~ b] $(b +(b))))
79```
81#### Examples
83```
84 > (ind:po 'zod')
85 [~ u=0]
87 > (ind:po 'zam')
88 ~
90 > (ind:po 'del')
91 [~ u=37]
