Hi Tseepra, Well, are you using Windows or Linux?: In Linux you can start IDLDE with a language switch, in this way: idlde -nl en where "en" is for English, and "-nl" is the switch: Syntax: idlde -nl locale Selects a different locale (language). Locale is a two-letter abbreviation, such as en (English), fr (French), it (Italian), or ja (Japanese). In Windows you will need to modify the calling setting to the IDL icon, for example: if you righ click in the IDL icon, and select Properties from the menu, you will need to change the "Target" to include the language switch: "C:\Program Files\ITT\IDL70\idlde\idlde.exe" -nl en Cheers, Fernando
