+====== Simplifying INP files - refining on 1000s of patterns simultaneously (Version 6) ======
+Refining on 100s or even 1000s of diffraction patterns simultaneously can lead to large bulky INP files comprising 100s of 1000s of lines of text. However, such a large INP file can be reduced to a few dozen lines by using the local keyword together with "for xdds {}". Here's an example for three data files:
+	xdd SOME_FILE_1
+	xdd SOME_FILE_2
+	xdd SOME_FILE_3
+	'-----------------------
+	out_refinement_stats
+	approximate_A
+	out "output.txt"
+	'-----------------------
+	for xdds {
+		start_X  3.9
+		finish_X  11.3
+		LP_Factor(17)
+		convolution_step 2
+		Rp 217.5
+		Rs 217.5
+		CuKa2(0.001)
+		'-----------------------
+		local bkg0 0

+		Out(bkg0,"bkg0 %e ", "%e ")
+		Out(bkg1,"bkg1 %e ", "%e ")

+Note, how the bkg parameters are handled.
