FileinMatrix3by3: PROC [f: IO.STREAM] RETURNS [mat: Matrix3by3];
RopeNotOnTop: SIGNAL [position: NAT, wasThere: Rope.ROPE, notThere: Rope.ROPE];
Reads in one character from f. Complains if it is not c.
Signals RopeNotOnTop if some other char is on top.
ReadReturn:
PROC [f:
IO.
STREAM];
Convenience function. Equivalent to ReadChar[f, IO.CR];
ReadKeyWord:
PROC [f:
IO.
STREAM]
RETURNS [keyWord: Rope.
ROPE, good:
BOOL];
Reads a rope until a ':' or <CR> are encountered. If CR is encountered first, then good is FALSE since ":" is expected after a keyword.
Reads a rope UNTIL <CR> is encountered. Used to read Solidviews version rope.
The <CR> character is tossed out.
A convenience function. Equivalent to ReadBlank[f]; n ← ReadNAT[f];
ReadPoint3d:
PROC [f:
IO.
STREAM]
RETURNS [point3d: Point3d];
Assumes the next rope on the stream will be of the form "[<real1>,<real2>,<real3>]".
ReadPoint2d: PROC [f: IO.STREAM] RETURNS [point2d: Point2d];
ReadPoint2dAsPoint3d:
PROC [f:
IO.
STREAM]
RETURNS [point3d: Point3d];
Assumes the next rope on the stream will be of the form "[<real1>,<real2>]". Fills in point3d[3] with zero.
