example(((val2 = val1 * 2)))
assigns twice the value of tt($val1) to the parameter named tt(val2).
If the expansion of tt($val1) is text rather than a number, then when
tt(val1) is referenced that text is itself evaluated as a math expression
as if surrounded by parentheses `tt(LPAR()$val1)tt(RPAR())'. Expansion
continues until there are no more parameter references, a number has
resulted, or an expression error occurs.
An internal integer representation of a named parameter
can be specified with the tt(integer) builtin.
