keyword_set bug or feature [message #4216]

Thanks to those who responded to my ? concerning common blocks.

I just can across another 'feature' and was wondering if others felt
that it is really a 'bug' or if there is some way to over come it. It
has to do with keywords in functions or procedures. I use several and
check to see if the are set using

IF NOT(keyowrd_set(key)) THEN BEGIN
;set a default value here
ENDIF

The problem comes in if the user wants to set key = 0. If so then it
appears to the above test that the keyword is not set even though in
the function call the user typed

Result = somefunction(var,key=0)

What gives? Can I just add key = key + 1 and key = key - 1 around the
testing if statement?

Any other suggestions appreciated.
