Hello All, I have a simple C-application under linux that dumps a file following the fortran format (for reason of compatibility with another fortran code): -5.8500E-06 6.1379E-06 3.7700E+00 -8.6851E+00 1.6587E+01 1.7789E+07 1.2686E+01 -2.0000E-04 1 5 7.8154E-04 -7.6327E-05 7.7007E-04 1.3974E+02 -2.4259E+03 -2.3236E+04 1.5000E-03 -2.0000E-04 1 3 -1.0805E-04 7.5232E-04 -9.3542E-04 2.4451E+03 4.1420E+02 2.0763E+04 -1.5000E-03 -2.0000E-04 1 3 1.6066E-03 -1.6012E-04 1.4611E-03 2.3279E+02 -4.7181E+03 -4.0685E+04 3.0000E-03 -2.0000E-04 1 3 -2.9795E-05 1.6006E-03 -1.7185E-03 4.7022E+03 5.9128E+02 2.1321E+04 -3.0000E-03 -2.0000E-04 1 3 2.3934E-03 -6.3027E-04 1.9306E-03 1.2812E+02 -7.1726E+03 -5.6825E+04 4.5000E-03 -2.0000E-04 1 3 Under linux I used the syntax: fprintf (fh," %' '.4E %' '.4E %' '.4E %' '.4E %' '.4E %' '.4E %' '.4E %' '.4E %' 'd %' 'd\n", X[i][0], X[i][1], X[i][2], X[i][3], X[i][4], X[i][5], X[i][6],X[i][7], (int)X[i][8], (int)X[i][9]); which work well. When I try to compile this under windows it does not work anymore but dumps the "'" in the output file. Anybody has some suggestion? Thank you in advance, -- Philippe Piot.
