+## Remarks
+
+Each string in the `sourceTexts` parameter is the equivalent of a single source file. There must be at least one `sourceTexts` element.
 
-The file names in the sourceTextNames parameter are used for compiler diagnostics and debug information. The array is required, but it can be locally overridden by use of the \#line directive. The array must have the same number of elements as the sourceTexts parameter.
