Hi All

I have a data which is organized in the following way

obj1 12.5
obj1 14.5
obj1 15.4
obj1 14.0
obj1 12.5
obj1 14.5
obj1 15.4
obj1 14.0
obj1 12.5
obj1 14.5
obj1 15.4
obj1 14.0
obj2 12.5
obj2 14.5
obj2 15.4
obj2 14.0
obj2 12.5
obj2 14.5
obj2 15.4
obj2 14.0
obj2 12.5
obj2 14.5
obj2 15.4
obj2 14.0

I want to extract all the values associated with obj1 and write them in a separate array. In a similar way for the obj2. Please help.

Thanks
Tanvir

readcol,"data.dat",obj,value

for i=0; n_elements(obj)-1 begin
if obj(i)='obj1'
forprint,obj(i),value(i),text='obj1.dat',F='(A,1x,F)'
else
forprint,obj(i),value(i),text='obj2.dat',F='(A,1x,F)'

endfor

Then you can store the value of files obj1.dat and obj2.dat in different array using readcol or openwr.
This may be the easiest way, else there might be so many other ways which others can help....

Thanks

readcol,"data.dat",F='(A,1x,F)',obj,value

for i=0; n_elements(obj)-1 do begin
if obj(i)='obj1' then
forprint,obj(i),value(i),text='obj1.dat',F='(A,1x,F)'
else
forprint,obj(i),value(i),text='obj2.dat',F='(A,1x,F)'

endfor
