Hi,

Please check the following code. I want to print the data from the
first line, but when i assign t=dummy(0) it taking 5th value from the
dummy. So please help me on this.

dummy = strarr(5)

openr,lun,'cdays.dat.old',/get_lun

for j=0, 2 do begin
readf,lun,dummy
;readf, lun ,dummy(0)
t=dummy(0) & print,'T val is', t
print,dummy
endfor

free_lun,lun

Output:

s)
