Display Sequential Function Execution

I am having two different function in my script. When control is at first function I do not want to execute another function. How I can do that?
Help is highly appreiated as I am not sure How I can do it in Unix?

I'm not sure if I understood your question correctly. See if this helps:
function func1 {
    # statements
    # statements
    echo "func1"

function func2 {
    if [ $f1_flag == 1 ]
        echo "func1 has already run. So, exiting from func2"
        return 1
    echo "func2"
    # statements
    # statements

Unless you call funcx from within funcy, there's no chance they execute simultaneously in a single process. Or are you talking of multiple processes?
