hi to all
i was programming in assembly code in fragment program
i want to ask
let this code
Code :
!!ARBfp1.0
PARAM c = {1.0,0.0,0.0,0.0};#Red
MOV result.color.xyzw c.xyzw;#Red to color
END
it give red color to the object where the progs call aplied
and in that code

i can punch this lines before MOV and after first line
Code :
PARAM a = {0.0,0.0,0.0,0.0};#all zerowed
PARAM b = {1.0,0.0,1.0,0.0};#not all zerowed
but if after that i put
Code :
MOV b,a;#b=a
then red color is not on object it was may removed/black in color
i want to ask in assembly code is there limit that
MOV(assignment) only done at once when second time seen it ignored
or
if the parameter not used are assigned then code not works.
