I wrote this little procedure for setting default values
that I use a zillion times a day:

PRO defaultarg, arg, defval, VALUEGIVEN=valuegiven

IF N_ELEMENTS( arg) EQ 0 THEN BEGIN
arg = defval
valuegiven = 0
ENDIF ELSE valuegiven = 1

END

then use it like this:

PRO somepro, arg1, arg2, KEY1=key1

defaultarg, arg1, 0
defaultarg, arg2, 'test'
defaultarg, key1, 2343d8

...

END
