| ERROR | previous use of string (at line string) conflicts with this use |
| CAUSE | While looking for prior declarations of a variable, constant, or label, the compiler found another declaration with the same name in the same scope. Or, the headers of subprogram in a package specification and body were not identical. |
| ACTION | Check the spelling of the variable, constant, or label name. Also check the names of all parameters and exceptions declared in the same scope. Then, remove or rename the object with the duplicate name. Or, change the headers of the packaged subprogram in the package specification or body so that they are identical. |
