Hello All,
How can I append contents into a file using forprint?
What I want to do...
For eg.
a=findgen(100)
b=findgen(100)
forprint, 'Numbers are:', text='tt.dat'
forprint, a,b,text='tt.dat'
I want all these to be appended in same file named tt.dat here.
How can I do??

Right now, you have to open the file yourself, set !TEXTUNIT to the unit number and use TEXTOUT = 5 when calling forprint
http://idlastro.gsfc.nasa.gov/ftp/pro/misc/forprint.pro
For example
openw,12,'test.dat'
!textunit = 12
forprint,indgen(12),text=5
forprint,indgen(5)^2,t=5,/nocomment
close,12
I should probably just add an /append keyword to make it a little more straightforward. --Wayne
