   It is also simply called an \firstuse[---]{evaluable parameter}.
   An evaluable parameter does not change during transient analysis, with a value either determined during translation (similar to having prefix \lstinline!constant!, and is then called an \firstuse[parameter!evaluated]{evaluated parameter}) or by the initialization problem (similar to a \willintroduce{normal parameter}, see item below).
