Hi- how can I get strings in & out of subroutine records?
It appears that the sub record tries to convert all its inputs
to "double" before calling the user function, and complains if it
fails. All I want is to read/write actual strings from inside
the function.

Right, you can't use the INP/OUT fields of a sub record for anything
other than doubles. As Andy Foster has said you could use a genSub
record, or if you only need one string you could use the psub->desc
field of the regular subroutine record (although it's only 28 characters
long). You could also consider writing your code as device support for
the stringin and/or stringout records.
