[Info-vax] VMS Basic strings class D vs class S

[Arne Vajhøj]

If I have understood it correctly then VMS Basic
strings use class D descriptors.

That is very nice.

But what happens if non-Basic code call Basic
code with a string using a class S descriptor?
For input/read? For output/write?

Does the Basic runtime call some STR$ function that
understands the difference between S and D and handle
A properly? Or will I get a runtime error due to invalid
string?
