Debugger Guide
Hidden Procedure Files
The Debugger ignores any procedure file (hidden procedure) whose filename begins with an underscore ( _ ). Although you can execute a hidden procedure, it is hidden from the Debugger in several ways:
- A hidden procedure never enters the Debugger context and does not honor any breakpoints that you set in it.
- The Debugger never displays the debug listing for a hidden procedure.
- While a hidden procedure executes, all procedures above it in the procedure call stack are also hidden from the Debugger as well, whether or not they are hidden procedures themselves.
The Progress ADE tools that invoke the Debugger use hidden procedures to keep the tools themselves invisible to the Debugger. You can use the same technique when writing your own development tools that invoke the Debugger.
