Creating an EP Curve in mel using the position of two joints

[coyote12]

Hi,

I am having trouble finding the correct MEL syntax to create a curve based on the position of two joints. I keep getting error parsing argument when telling it to make the curve.
my code is as follows

//getting the point locations
vector $startPoints[] = xform -q -t -ws LT\_Shoulder\_Bind\_Jnt;
vector $endPoints[] = xform -q -t -ws LT\_Elbow\_Bind\_Jnt;

//printing to confirm the variable
print $startPoints;
print $endPoints;

//one point curve command with the vectors inserted to be the curve points.

curve -d 1 -p $startPoints -p $endPoints -k 0 -k 1 ;

Why is this giving me the  // Error: line 1: Error while parsing arguments. // ?

The vector type is almost always useless in mel

vector $startPoint = `xform -q -t -ws LT_Shoulder_Bind_Jnt`;
vector $endPoint = `xform -q -t -ws LT_Elbow_Bind_Jnt`;
 
curve -d 1 -p ($startPoint.x) ($startPoint.y) ($startPoint.z)
           -p ($endPoint.x) ($endPoint.y) ($endPoint.z) -k 0 -k 1 ;

PS: Please don't comment like you would be a programming textbook .  Good comments are fine when you need them but comments always linger after your code goes forward. A incorrect comment is far worse than sloppy code. Since your comment is just extra stuff to read it always falls into problem category. Try to make the code understandable by form instead of by comment if you can.  So use functoin names as comments, and comment only highere level code.
