Hi,

I just began learning IDL, and am not understanding why the following is
not producing the string (20111021):

---<--------------------cut here---------------start------------------->---
IDL> caldat, julday(1, 294, 2011), mon, day, year
% Compiled module: CALDAT.
IDL> print, year, mon, day
2011 10 21
IDL> print, string(year) + string(mon) + string(day)
2011 10 21
---<--------------------cut here---------------end--------------------->---

I thought that the string() function would coerce the numbers to a
string, and then the concatenation operator ('+') would join them
together, but this is not happening. What am I missing?

Cheers,
