There wasn't a clear explanation given why support for it was dropped, that was just my guess... > Nice idea of yours. Does that work for not-set, or for not-true? Well, I'd envision it as non-set, there's already the C-like ? operator for true/non-true, which is sort of a shorthand for an if/else combination. By coding it as a set-if-not-set function, you avoid the if/else combination as well as a function call to test if a variable is set. I tried looking at the Zend source and lets just say its been WAY too long since I've used yacc to figure out how to add it, even to play around with how useful it would be. Any comment from the Zend-gods? I'm not sure where to submit it for a suggestion, since its not a PHP feature but a Zend feature... - George -- email:dotorg@bangsplat.org;url:www.bangsplat.org;uin:153182;aim:tgd98 GCS/GP/GS/GFA d- s+: a- C++++$ UL++++$ P+++$ L+++$ E- W++>$ N+@ !o K+++ w--- !O M-@ V PS+ PE Y+ PGP t-(+) 5- X++ R-(--) tv+ b+++ DI++ D++ G+ e* h r y++
