This is an inbuilt function function provided by PPWIZARD.
This function takes no parameters and returns the text of the current line being processed. The line returned is after macro expansion and may or may not be as read from the file. The line as read from the file is available using the GetFileLineBeingProcessed() call.
The returned line has been stripped of leading and trailing whitespace. This call would usually be called to remember details about a current situation which you may wish to report at some future stage.
If using this call you may also wish to use GetInputFileNameAndLine(), see this section for an example of these calls in use.
