The SPD ( https://vmssoftware.com/docs/VSI_Pascal_spd.pdf )
says:
VSI Pascal is an implementation of the Pascal language that accepts
programs compatible with either
level of the ISO specification for Programming languages - Pascal ([ISO
7185-1987]) as well as
(ANSI/IEEE 770X3.97-1987).
...
VSI
Pascal also accepts many features from the Extended Pascal standard
((ANSI/IEEE 770X3. 160-1989)
and (ISO 10206)).
...
Major Pascal Language Elements:
...
â—Ź STRING schema denoting variable-length character strings up to 65,535
characters
which I read as that string is supposed to be the standard (10206) string.
