Change the software is not an option because it's already parsing other
string. So I can not change the "if" statement to inverse it.

Also, I found a wierd syntax what would negate a string. Something like:


But, I got two problem with it. First it's not implemented in the language
the software is written in. And second, it requires to add something in
front of it to work properly. Like if I knew that the string I want to  
all have numbers before the potentially present "abc", I could write:


But as I want to accept all other strings except those that include "abc".  
not possible. btw, this doesn't work:

Generating the regexp with a scripting language would would be an  
exercise... I'm not sure I'm up to it though... :) If anyone have the time  
try, please let me know. Maybe Dr. Turnbull[2] can amaze us with his
