What happens if there is an error in the procedure named APPLICATION?

If the APPLICATION procedure is automatically triggered when the data base is opened and it has an error that boots me back out to the desktop how do I ever get at it to fix it? The answer is that there is a back door. There is a way to OPEN a data base that does not automatically trigger the APPLICATION procedure.

You can execute Thunderbolt and instead of going to the File menu use the Windows menu to go straight to DCL. Once there, key in the OPEN yourself.
An OPEN done from the command line does not trigger the APPLICATION procedure. An OPEN for the example data base would look like:

OPEN C:\THUNDER\APPS\EXAMPLE

Once in, use DEFINE to get at the APPLICATION procedure to modify it. The above example assumes that Thunderbolt was installed at C:\THUNDER. If not, then enter the correct drive and path leading up to .../APPS\EXAMPLE.
