```Thanks Bob and Patrick!

I agree with you using array of plots, but I "need" to put all the 6 curves
in the same plot window. Can you help me do that?

(Analyzing the curves might then be tricky, but piecewise (x-p) and (x-p)^2
is only an example function, actual piecewise function that I am trying to
plot is different, having many control variables to manipulate. I only need
to know the syntax so the query (adding one more control variable q if that
changes anything): )

a = {1 2 3 4 5 6}
The goal is to plot a piecewise function corresponding to each of "a"
values, with manipulate where control variable is p,q , and the function
for plot y versus x is:
y=x-p-q for x-p-q<a, and (x-p-q)^2 for (x-p-q)>=a i.e. 6 plots getting
manipulated simultaneously.

Again, Thanks for your help and I hope you will again respond to the query
quickly!

Best regards,

Vedhas
