suppose we have a PATH:
コード:

PATH=C:\WINNT\system32;C:\WINNT;C:\Program Files

and there is a folder, say "FreeAmp", under "C:\Program Files" then the script:

@echo off

if %~$PATH:1.==. echo HOGE

コード:

C:\> hoge.bat "FreeAmp"

Files\FreeAmp.==. was unexpected at this time.


WHY?

if FreeAmp.EXE in stead is used,
everything goes dandy.
