Progress Messages
Progress and applications written under Progress display several types of messages to inform you of both routine and unusual occurrences:
- Execution messages inform you of errors encountered while Progress is running a procedure (for example, a record with a specified index field value could not be found).
- Compile messages inform you of errors found while Progress is reading and analyzing a procedure prior to running it (for example, a reference to a table name that is not defined in the database).
- Startup messages inform you of unusual conditions detected while Progress is getting ready to execute (for example, an invalid startup parameter was entered).
After it displays a message, Progress proceeds in one of several ways:
- Continues execution, subject to the error processing actions which you give, or are assumed, as part of your procedure. This is the usual action taken following execution messages.
- Returns to the Procedure Editor (or other tool from which you ran the procedure) so that you can correct an error in a procedure. This is the usual action taken following compiler messages.
- Halts processing of a procedure and returns immediately to the Editor or other tool.
- Terminates the current session.
Access Progress Help (press HELP) if you do not understand a message. If you encounter an error message that terminates Progress, the message ends with a number in parentheses. Carefully note that number before restarting Progress. In all other cases, Progress keeps track of messages that it displayed recently.
