So CFIF A AND B will not bother to evaluate B if A is false, and CFIF A OR B will not bother to evauate B if A is true. 0 0 2005-01-28T12:15:34 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/expresa5.htm#23172 Will CF evaluate both sides of a boolean AND expression if the first part is false? (short-circuiting). I remember reading this somewhere, but it seems to me that it should be more visible in the docs. 0 0 2004-10-29T12:12:27
