Dear Scott Yellig,
Thank you so much for the reply and for your query i would like to inform you that i was referring to the INSTRUMENTS I/O example that comes with LABVIEW 5.1 ( you can go there by starting the LABVIEW then move on to Examples and there you will find INSTRUMENT I/O , probably among the last 5 in the list).
We are actually threee students (samura = saleem, munib, rauf) having some problems in understanding the addition of sub vi's to a VI and how to relate them. We are new to LABVIEW and want to explore it to full potential as we have found it to be the best tool of its kind in the market.
Once again thanking you for the reply and interest you shown.
Regards,
Samura
