1 program into another

[ashishbathini]

Hi guys here is my problem ...


this is the source code I Have , honestly I hav no idea how it works bcos its too complicated for me ....

but my problem is ... i hav a freq comonent in it .... what I have to do with it is ... I need to take the output of the second program (which is the freq component ) and this Shud be the input for the program A

i am not sure bout the freq component too ....since i am unable to understand the program ... and even if I get the program where i shud insert it
