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 http://groups.google.ca/groups?hl=en&lr=&ie=UTF-8&threadm=7BB320A15C3A624384 97BE5D0A74846803795580%40m-phppo-1.phppo.cdc.gov&rnum=2&prev=/groups%3Fq%3Di if%26hl%3Den%26lr%3D%26ie%3DUTF-8%26group%3Dcomp.soft-sys.sas%26sa%3DG%26sco ring%3Dd for a clue.

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
