Writing data into files using VHDL Textio

Question

Hi 
I was trying to write nos. from 1 to 8 into a text file using the below program.
process
type IntegerFileType is file of integer;
file data_out: IntegerFileType ;
variable fstatus: FILE_OPEN_STATUS;
variable coun: natural:= 1;
begin
file_open(fstatus,data_out,"myfile.txt",write_mode);
for i in 1 to 8 loop
write(data_out, coun);
coun := coun + 1;
end loop;
file_close(data_out);
wait; -- an artificial way to stop the process
end process;
But getting the below attached result..
Can you please help me out what could be wrong with the program.
Thanks & regards

Answer 1

Do you want the numbers in the file to be human readable ASCII?
Then you'll need to convert your coun to a string. 
declare another variable of type line (type access to string).
do a write() to the line, then a writeline() to the file.
natural'image(coun) will convert coun to a string.
Google should help you find example code that will help.
