ReadListOfRope: PROC [f: IO.STREAM] RETURNS [ropeList: LIST OF Rope.ROPE];

Reads a list of words separated by commas or spaces.

ReadArrayOfReal: PROC [f: IO.STREAM] RETURNS [reals: SequenceOfReal];

Reads a list of REALs enclosed in square brackets, separated by spaces, tabs, commas, or semi-colons. For instance [3.5, 2.6, 1, 4. 3.0 ] returns a list of 5 real numbers.
