Joe,
Do you mean that the addresses have "descriptions, but no "symbols" (descriptive text assigned to each address?
If so, the only way to move the "descriptions" for the description database to the symbol database is manually. You will have to edit them to meet the requirements for symbols: No two the same, not longer than the Smbol Length set in "Tools, Options, System Preferences", and no spaces in the text. Because of these restictions, I use descriptions more than symbols, except where there is an HMI involved.
In the RSLogix Cross-Reference Report, I see Address, Description, and all File & Rung Locations where this address occurs in the program. Symbols are also shown if the Address has a symbol assigned to it.
