Read::readx
ReadList::readx
Skip::readx
The second argument in ReadList does not specify anything to read:
Module[{s = StringToStream["one two three"], result},
result = ReadList[s, Word[]];
Close[s];
result
]This shows a valid format specification in ReadList:
Module[{s = StringToStream["one two three"], result},
result = ReadList[s, Word];
Close[s];
result
]
