The ALP Messages File

Nearly every message displayed by ALP at run time is stored in a separate message file. The exception to this rule are messages that are displayed if the message file cannot be opened: ALP ends if one of these messages is displayed.

When ALP starts, it determines the name of the message file by creating a name of the form <BaseEXE>.msg (see BaseEXE). Once ALP knows the name of the message file, ALP searches the following directories in the following order for the file:

• Current directory
  
• The directory contained in the BasePATH internal variable
  
• Each of the directories specified in the BaseEXE internal variable
  
• Each of the directories specified in the PATH environment variable
  
• Each of the directories specified in the DPATH environment variable
