Changeset 385

Timestamp:

Nov 20, 2007, 12:04:07 AM (16 years ago)

Author:

イグトランス (egtra)

Message:

例外クラスの実装。ExceptionTestでSystem.Exceptionを使用するようにした。
StringBuilderでコメント化されていた例外を投げる処理を有効にした（除OutOfMemory）。
Str$の実装にSPrintfなどを使用するようにした。
毎回Object.ReferenceEquals(xxx, Nothing)と打つのが面倒なので、IsNothingを導入。
