well, the easiest way to find out whats fastest is to write a test app (all of 5 lines of code).. looping 1 billion times (which is what it takes to get a reasonable answer), length(str)=0 is 3 times slower than str=''.
not only that, but -you've doubled the number of characters you need to read -youve added an extra level of brackets -and now if someone else goes to read it, they'll wonder why you've done it that way.. and now myles has given the asm too :-) --- Neven MacEwan <[EMAIL PROTECTED]> wrote: > Hi All > > Whats the fastest way to test for an empty string > I just get the feeling that String = '' is not good practice > > Regards Neven > N.K.
