Syntax rules for `variable`
I have last printing of MetafontBook (8th printing, Volume C). Since that printing (and hence since all other printings), two very curious corrections appeared in errata:
1)
Question concerning this correction:
A suffix is either an empty set, or any number of <tag>s or <subscript>s in any combination (see syntax rules on p.54). So, a <subscript> is a subset of suffix. Therefore it is not clear why it is said
suffixed or subscripted
as if they were separate properties.
2)
It is worth to put here definition of <suffix list>:
<suffix list> -> <suffix> | <suffix list>,<suffix>
Question concerning this correction:
What is any concrete specific example for this case?
