#### 6.1.32 `setparam`

Usage:

       setparam [-type byte|short|int|long|float|double|boolean|string]
                [-desc <descrip>] [-unit <units>] [-ucd <ucd>]
                [-utype <utype>] [-xtype <xtype>]
                <pname> <pexpr>

Sets a named parameter in the table to a given value. The parameter named `<pname>` is set to the value `<pexpr>`, which may be a literal value or an expression involving mathematical operations and other parameter names (using the `param$<name>` syntax). By default, the data type of the parameter is determined by the type of the supplied expression, but this can be overridden using the `-type` flag. The parameter description, units, UCD, Utype and Xtype attributes may optionally be set using the other flags.
