Need help in understanding how the data is transcribed here from image to numbers. Here is the code:
filename decomp "C:\Users\Richard Boire\Desktop\train-images.idx3-ubyte";
data train_images;
infile decomp recfm=n;
*input var $256.;
input var PIB1.;
run;
proc print data=train_images(obs=10);run;
Here is the output(printed off 1st 10 records)
Obs var
1 0
2 0
3 8
4 3
5 0
6 0
7 234
8 96
9 0
10 0
These are the decimal values of each byte of the file you are reading.
This:
data _null_;
file "%sysfunc(pathname(work))\t.txt";
put 'A' '09'x;
run;
data _null_;
infile "%sysfunc(pathname(work))\t.txt" recfm=n;
input X pib1. ;
putlog X= ;
run;
yields this (under Windows):
X=65
X=9
X=13
X=10
