No fluid or dynamic variables in any standard before R7RS, and it is trivial to roll your own parameters provided they don't have to interact with threads: see R7RS.

For fluid variables, see the withdrawn SRFI 15.
Were fluid variables ever a part of any Scheme standard?
Were any dynamic-variable-style facilities before R7RS?
How does R6RS deal with dynamic variables - is the user expected to roll their own using dynamic-wind? I though parameterize was in that standard as well, but I looked again and it's not. Just some R6RS implementations have it.
