I am aware of the technique you suggested...unfortunately it is not optimal for me in this case. By placing multiple records in a single gnuplot command file, one window opens (I am running this under X) and I have to place it with a mouse click. Then, as I press enter, new plots come up in the same window until I get through all of them.
Using your suggestion, a new window opens for each instance...each would have to be placed with the mouse before plot generation. It would work, but in some cases I have a large volume of plots to look through and the extra mousing would slow things down too much.
Thanks for taking the time to answer
