I have a perl program (A) running and then I execute a new program (B) from within this program (A). I want to set the new program (B) execution to a low priority. After perl program B has run its course then the perl program A is activated once again. In the context of this I am not sure following statement is quite right (although I may need to be corrected on that).
I will look at your suggested code in this context. Thanks for that code by the way.
