I am having trouble understanding your problem..

In general I can say that is you are processing data and can only find out if a certain line contains the right data later one or more lines later on, then you could record the data into a variable. For example if you want to use printf(...) to print a value, instead you can use some_var=sprintf(...) to record an output line into a variable, and print this recorded variable (print some_var) one or more lines down when you are able to conclude that it was indeed the right value..

Hope this helps and/or makes sense...
