task body()
fork
seq1.start(sqr1);
seq2.start(sqr2);

You would have to provide more information about what you want to accomplish. Do you want to run the sequences in parallel? In series? What is wrong with fork/join that you can’t use it?

I need to run sequences randomly. I came to know there is another way to do it. but I am not aware how to do it.

You could instead use a randcase or a randsequence.
For the randcase it looks like

randcase
   2: seq1.start(sqr1);
   5: seq2.start(sqr2);
endcase

2 and 5 are weights. In this case seq2 will be started with a higher priority.
You could put the randcase in a loop. Then the sequences will be started repeatedly.
