unblank part of a trim

[trolltuning]

I'm building a VCD file from some DV footage. I'm using aviscript to build trim commands to join together about 30 clips. I will set a mask on it (which AviScript places before the ttrim commands) The last clip I need no mask. What is the simplest way to modify the script?

I'm working from memory as Avisynth is at my home computer and I'm at work but I believe the script is like this.
Avisource("instrvid1.avi")
Mask(44,44,0,0)
#I don't remember the resize command but its standard VCD size
Trim(200,1000),Trim(1200,2000),Trim(3200,10000),etc, Trim(64000,67000)

Assuming I want to remove the mask on the 64000 to 67000 clip what is the simplest thing to do?

Something like

clip = Avisource("instrvid1.avi")
clip2 = Trim(clip,200,1000)+Trim(clip,1200,2000)+Trim(clip,3200,10000)+...+
clip3 = Mask(clip2,44,44,0,0)

clip4 = Trim(clip,64000,67000)

clip3 + clip4

:) Thanks Wilbert. Now I see the advantage of using variables. So nice to be able to get this done in one shot and not have a bunch of avis eating up all my harddrive space.
