Thank you very much for that hint!! I was able to get what I needed by
using the writeu function.
This is what I did in case anybody else runs into this problem:

This first way that I did it I passed an array and wrote the
information from it into testidl.dat
OPENW, lun, 'testidl.dat', /get_lun
WRITEU, lun, array
FREE_LUN, lun

This second way of doing it I took the information from a .bmp file
and wrote it as wireframe.dat
file = FILEPATH('wireframe.bmp')
image = READ_BMP('/home/users/fjosuna/CASVU_ISS/wireframe.bmp')
OPENW, lun, 'wireframe.dat', /GET_LUN
WRITEU, lun, image
FREE_LUN, lun

Thanks again Jean!!
