Hi,

Using the following script to convert calendar date to day of year (test.pro):

FUNCTION calendar2doy, year, month, day
jd=julday(month, day, year)
caldat, jd, Null, Null, year
doy=string(jd - julday(12, 31, year - 1), format='(i03)')
RETURN, doy
END

PRO TEST
year=2011
mon=10
day=15
DOY=calendar2doy(year, mon, day)
RETURN
END

I expected the variable year in the TEST procedure to remain as defined (the long integer 2011), but this is what I see after calling the call to calendar2doy with a breakpoint at the RETURN line:

IDL> .run "test.pro"
% Compiled module: CALENDAR2DOY.
% Compiled module: TEST.
IDL> breakpoint,'test.pro',14
IDL> test
% Compiled module: JULDAY.
% Compiled module: CALDAT.
% Breakpoint at: TEST 14 test.pro
IDL> print, year
2012

What am I missing?

Cheers,
Seb
