Folks,
Hi,
I am running an IDL code like this
......
print, x
print, y
print, z
print, t
openw, lun, 'test.txt', /get_lun
printf, lun,x,y,z,t
free_lun, lun
........
x,y,z, t are float numbers.
What i want is like this:
1- first run: make a file like 'test.txt'and write the result to this file ('test.txt').
2- at the second run (and more), append the new x,y,z, t to the 'test.txt' file.
At the end, i need a text file that holds all of my data in single 'test.txt'...
Thanks for any kind of help in advance :)
Cheers,
Dave
