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 
	local bkg1 0
	local bkg2 0
	local bkg3 0
	local bkg4 0
	bkg = bkg0; = bkg1; = bkg2; = bkg3; = bkg4;
	Out(bkg0,"bkg0 %e ", "%e ")
	Out(bkg1,"bkg1 %e ", "%e ")
	Out(bkg2,"bkg2 %e ", "%e ")
	Out(bkg3,"bkg3 %e ", "%e ")
	Out(bkg4,"bkg4 %e ", "%e ")
	'-----------------------
	local ze_ 0.01
	Zero_Error(,ze_) 
	Out(ze_,"ze %e ", "%e ")
	'-----------------------
	str 
		space_group 206
		phase_name "Y2O3"
		TCHZ_Peak_Type(,0.03,, -0.001,, 0.0014,, 0,, 0.06,, 0)
		'-----------------------
		local !csl_ 40 min 3 max 100
		LVol_FWHM_CS_G_L( 0.89, 15, 0.89, 23,,,csl_,)
		'-----------------------
              	local scale_ 1.7e-010 min 1e-20
		scale = scale_; 
		'-----------------------
		local a_  3.61 min =3.6; max =3.62;
		Cubic(=a_;)
		'-----------------------
		site Y1 x 0.9   y  0        z  0.25     occ Y   1  beq  0.2
		site Y2 x 0.25  y  0.25     z  0.25     occ Y   1  beq  0.2
		site O1 x 0.3   y  0.1      z  0.3      occ O-2 1  beq  0.2
		'-----------------------
		Out(csl_,"csl_ %e ", "%e ")
		Out(scale_,"scale_ %e ", "%e ")
		Out(a_,"a_ %e ", "%e ")
}

Note, how the bkg parameters are handled.
