Thank you, let me explain you the situation:
1. I did the program first to run for one array, as follows:

archivo = READ_ASCII(FILEPATH('gv04.bit', ROOT_DIR='c:\',$
SUBDIRECTORY=['RSI','IDL55','lib']))

archivo = READ_ASCII(FILEPATH('gv04.bit'))
WRITE_TIFF,'gv04.tif',archivo.FIELD01
end

2. It worked for 50x50,and I actually produced the image. I tried the
same program but for 200x200, and an error message appears saying:
% Tag name FIELD01 is undefined for structure <Anonymous>.
% Execution halted at: $MAIN$ 5
C:\RSI\IDL55\lib\transform.pro

4. The image was not produced

5. The file of [50,50] is exactly like the one [200,200] except for
the size. When opened in Excel all the numbers of one row appear in
the same cell. If I change the extension, and open it in notepad, the
numbers appear separated by tabs. (Ascii file, isn't it??)

6. Then I used the following program to do it for 69 files:
files=FindFile('*.bit')
for j=0,N_Elements(files)-1 DO BEGIN
cadena2=string([j])
archivo = READ_ASCII(cadena2)
cadena = 'gv' + string([j]) + '.tif'
WRITE_TIFF,cadena,archivo.FIELD01
endfor

end

7. I tried: print, Archivo. The 255 and zeros appear (not properly
aligned, zeros have more decimals than 255s),however, this did not
show when opening the original file with excel or notepad...I think
the problem is here....not?

8. If that is the case, how can I get rid of those extra zeros that I
didn't creat!!??

Regards,
Adhara
