Unknown data type [message #42107]

Hello,

The files I want to read haven't any typical format. Each file has
information in the first line (like number of rows and columns), but
anything about data typeï¿½

So, I followed the tips of David. I carried out a "trial read" usingï¿½

Data_type=integer ; I assume all the files are integer
ON_IOERROR, bad
OPENR,lun, arq, /GET_lun
test = make_array(nc, nl,/integer)
READU, lun, test ; reading the file into an integer array
GOTO, Ok
bad: data_type=byte ; if the file coudn't be read into an integer
array
Ok: FREE_LUN, lun

As I told you first, I have only two possible data types: byte and
integer. So, using it, I could solve the problem.

Thanks David and others,
Julio
