The Procedure Name input box is where you type in the name of the procedure you want to locate.

You use the Search│Locate Function command to find a declaration of a procedure, not its instances.

Locate Function is particularly useful for reviewing the definition of a procedure, as well as for finding locations where you want to set breakpoints and watches.

You can enter the name of a procedure or use the history list to select one you've used previously.

You can only type in procedure names that have source code in a file that has been compiled with debug information.

Library procedures can't be located because their source code is unavailable.
