This sounds very similar to the IFN and IFC functions.

IIF is an MDX function:
http://support.sas.com/onlinedoc/912/getDoc/mdxag.hlp/a002607754.htm
"IIf returns one of two numeric or string values that are determined by a
logical test.
IIf(<Logical Expression>,<String Expression1>,<String Expression2>)
Note: If a numeric value is returned, then it is a numeric function, not a
string function."
We always used IFF for the "strong if" in college.

Practice defensive programming!
Expected data conversion issues, i.e. via INPUT statement or function can be
dealt with elegantly using the ? or ?? modifier.
e.g. numeric_fld = input(char_fld, ?? 12. );
As far as I know, there is no way to selectively turn off certain errors in
SAS. The onus is on YOU to write robust code.
if blah then
erb = gak / blah ;
else
erb = .;
I believe v9.1 has an implementation of "if and only if". See

Subject: Turning off only specific errors
I have a couple programs that have tons of predictable errors, like reading
in a number variable when the data value is missing or text (in which case,
I want it to return a missing value) and things like that. I set "errors=1"
so it won't repeat it forever, but given how many files I read, process,
etc. my log file still gets bogged down with error messages so I have
trouble finding the errors I really care about. Is there a way to tell says
to not report any errors of a certain type (say, division by zero, missing
substr() parameter, etc.).
Thanks,
Jim
