Dear all
I have a problem to reading a binary file that has been written by Fortran program. how I can read the binary file from fortran program. I run this command and i got this error. please see it my problem and give me solution. I am appreciating in advance. please look the program.
infile = 'C:/Users/fadaei/IDLWorkspace80/DEM.dat' ;Input file name
IDL>
IDL> OPENR, iunit, infile, /GET_LUN ;Open input file
IDL>
IDL> n = 0 ;Make n a LONG
IDL> m = 0 ;Make m a LONG
IDL> READU, iunit, n, m ;Read n and m
IDL>
IDL> i = LONARR(n, n, n) ;Create i array
IDL> z = FLTARR(m, m) ;Create z array
IDL> b = BYTARR(m, m) ;Create b array
IDL> READU, iunit, i, z, b ;Read i, z, and b
IDL>
IDL> FREE_LUN, iunit ;Close output file
IDL>
IDL> HELP, n, m, i, z, b ;Print variable info
IDL> PRINT, z[0:3,0:3] ;Print part of z
