 | MEL: curves, pivots, and points

Ok,
How do I place the rotate pivot and scale pivot of the curve at the position of the first CV of that Curve????

With the Rotate or Scale tool active, press 'Insert' to get the 'move pivot point' manipulator. Then just hold 'C' (for 'snap to curve') and click on the curve, then slide the pivot along until it sticks to the end. Let go, and hit 'Insert' again. Voila.

Uh, yeah, I can do that...
But how do you do it in MEL... Like the subject says. Sorry if I wasn't as Clear as I should have been, my bad.
Just for the record let me restate: How does one, in Maya, with the MEL scripting language, move the pivot point of a curve to the cv[0] point, aka the origin of the curve, i.e. the first CV.
anyone????
sincerely,
Clear

My apologies, Clear.
float $posx = `getAttr curve1.controlPoints[0].xValue`;
float $posy = `getAttr curve1.controlPoints[0].yValue`;
float $posz = `getAttr curve1.controlPoints[0].zValue`;
move -a $posx $posy $posz curve1.scalePivot curve1.rotatePivot;

Steve,
Thank you, so close, let me bring it on home, yo!
//-move the pivot point of a curve to it's first CV-//
float $posx = `getAttr curve1.controlPoints[0].xValue`;
float $posy = `getAttr curve1.controlPoints[0].yValue`;
float $posz = `getAttr curve1.controlPoints[0].zValue`;
float $curvex = `getAttr curve1.tx`;
float $curvey = `getAttr curve1.ty`;
float $curvez = `getAttr curve1.tz`;
$posx += $curvex;
$posy += $curvey;
$posz += $curvez;
move -a $posx $posy $posz curve1.scalePivot curve1.rotatePivot;
//-END-//
Those extra 6 lines are if your curve has moved.
-Clear
p.s. extra points for anyone that can do this in less lines.

Ooooh. Very nice work!
Now how about:
float $position[] = `getAttr curve1.controlPoints[0]`;
float $curvePosition[] = `getAttr curve1.translate`;
$position[0] += $curvePosition[0];
$position[1] += $curvePosition[1];
$position[2] += $curvePosition[2];
move -a $position[0] $position[1] $position[2] curve1.scalePivot curve1.rotatePivot;
...at a svelte six lines.
Anyone want to take it any further? :)

Have you ever taken a look at Melbotwars (http://www.melbotwars.com)?
If this is a melscript spitting contest... then that must be the melscript OLYMPICS. ;D
