I am not sure if the EOF() function in IDL version newer than 5.2
really has some problem or some setting has to be adjusted.
I just want to read data from the stdin and automatically stop at
the end-of-file. The following codes work for version 5.2 but not
for version 6.0 nor version 7.0.
Just want to know if anyway around it ?

;--- test_eof.pro -----------------
pro test_eof
a=float(1)
while not eof(0) do begin
read, a
print, a
endwhile
end
;---- end of 'test_eof.pro' -----
#######################
;---- test_eof.idl ----------------
.compile test_eof
.run test_eof
exit
;---- end of 'test_eof.idl' ------
#######################
When I ran it using "idl test_eof.idl"
I got error at the end of my input.
