fwrite question on reading

[Shun Jie Liu]

Hello, I tried to use fwrite to get a data file and try to read it but i got a distorted view from the newly created data file. I wonder is it my control file or something else thats causing the problem. Anyone could help shed some light on my problem ? 
 
Thank you

I create the sample.dat using 
 
set fwrite sample.dat
set gxout fwrite
d t2
disable fwrite
