Hi All

I have .dat file which is binary format unsigned integer 32. The file is 5000 by 5359 and I use the following to read the file in IDL as a complex numbers

array_HH = make_array(5000, 5359, /dcomplex, /nozero)

filename_HH = ('C:\Users\asus\Desktop\IDL_PROJECTS\20151021115853_11_SAR_C PLX_0_pres_8.dat')

OPENR, importUnit, filename_HH, /GET_LUN

READU, importUnit, array_HH

CLOSE, importUnit

FREE_LUN, importUnit

Absloute_Value_HH = ABS(array_HH)

Image_HH = Absloute_Value_HH^(0.7/2)

My question is I want to save the file after editing as .dat file with the same format and saving it in the same file not a new file. How can that be done so once I open it again, I open it the same way

Regards
