Returns an unscaled real fixed binary value specifying the number of data items transmitted during the last GET or PUT operation on the specified file-reference.
COUNT(x)
x is a file-reference. The file must be open and have the STREAM attribute.
None.
Description
The count of transmitted items for a GET or PUT operation on x is initialized to zero before the first data item is transmitted, and is incremented by one after the transmission of each data item in the list. If x is not open in the current program, a value of zero is returned.
If an ON-unit or procedure is entered during a GET or PUT operation, and within that ON-unit or procedure, a GET or PUT operation is executed for x, the value of COUNT is reset for the new operation. It is restored when the original GET or PUT is continued.
