Thank you I appreciate your time and input. This is what I'm trying to do.

 Code:
If @USERID = "601Mgr_03" GOTO RM601C
endif

:RM6010
writevalue ("HKEY_CURRENT_USER\Environment", "Station", "601100", "REG_SZ")
writevalue ("HKEY_CURRENT_USER\Environment", "Extension", "601100", "REG_SZ")
writevalue ("HKEY_CURRENT_USER\Control Panel\Mouse", "SwapMouseButtons", "1", "REG_SZ")
goto Common

:Common
writevalue ("HKEY_CURRENT_USER\Environment", "Formcache", "C:\Cache\cache%station%", "REG_SZ")
writevalue ("HKEY_CURRENT_USER\Environment", "Extension", %Ext%, "REG_SZ")
goto end
