VBSからPowerShellへ (1)変数定義の強制

Last updated at Posted at 2019-05-04

VBS(VBScript)からPowershellへの移行に関して、作業用の備忘録。

変数定義の強制

VBSでよく出てくる未定義の変数を禁止するための
Option Explicit

これはPowershellの場合は
Set-StrictMode -Version 2.0
となる。

ただし、Option ExplicitSet-StrictModeは方向性として完全一致というわけでなく、さらに1.0と2.0ではチェック対象の厳格さが異なるが、通常はSet-StrictMode -Version 2.0を使えばいいかと。
