And also fixed in the description of VARYING further up.

If I were to guess about why, then I believe it is historic
reasons. varying of char has been there since like forever.
string was added with ISO Pascal support later.

 I suspect that's close, but ISO Pascal doesn't have a 'VARYING'
array type, either.

I am saying that VMS Pascal had VARYING before ISO existed. A
VMS specific (or DEC specific??) extension.

I suspect you're referring to what ISO calls "Extended Pascal"
(ISO 10206); ISO Pascal (ISO 7185) doesn't support a `String`
type of either the VSI Pascal form or the Turbo
Pascal/Delphi/FreePascal form, only manifest string literals and
`packed array [1..n] of char`.

Yes, 10206.
