hi,

    iam not asking vb scripts r java script. it is realted
to code. it is may be commands r sytax r library functions..
exactly i donot know thats y i kept the question. u
understood what i asked.

If we develop a Test Script in QTP irrespective of 
Actions... are called as "Test Script"

it means only one Script available in one Test. until 
unless create new Test, any no. of Actions or Functions or 
procedures.... etc in one Test called Test Script.

Only One Script in QTP Test.

if you want to see Scripts individually according to 
Actions. Go to your Saved Test Folder and open Action0, 
Action1, Acion2.... etc., each and every Action contains 
its own Test script (.mts) Mercury Test Script. 

But we should not say in interviews as no. of Actions 
contains no. of Scripts. it is wrong answer, we should say 
only one Test Script in one Test in QTP
