Passing anything other than a character data type as the second parameter to the SYS(2014) function does not result in a "Function argument value, type, or count is invalid" error even though the data type is incorrect. Under some circumstances, passing an incorrect data type may cause a Fatal Exception error.


You must check the data type of the second parameter before passing the value to the SYS(2014) function. Then you can use the TYPE() function to verify that the data type of this parameter is character.


Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.


Steps to Reproduce Behavior

  1. Run the following line of code from the Command window:
RESULTS: You do not get the error message mentioned in the SYMPTOMS section, and a Fatal Exception may occur.
