| ERROR | package string used as variable reference |
| CAUSE | A package was referenced in an expression as if it were a variable or function. Either the name of the variable or function is misspelled or the reference is not fully qualified. For example, to call the function my_function, which is stored in package my_package, dot notation must be used, as follows: ... my_package.my_function ... |
| ACTION | Correct the spelling of the variable or function name or use dot notation to reference the packaged variable or function. |
