[quote=JamesD] [quote=siria] PS: Noticed that if one of the arguments for "and/or" is not a variable, but some action like "index(...)", then additional brackets () are needed around both arguments left and right, even if the other one is just a variable. [/quote] Yes, another good find for you. This becomes complex very quickly. Look at what I had to do to get the number of ()s to be correct. [code] $_ASring = "hijkl"; ## |-------------------------------------------------------------------------| ## |----------------------| |----| |------------------| |---| ## |------------| |--------| while ( ( index($_ASring, "j") ) != ( -1 ) and ( length($_ASring) ) > ( 2 ) ) { alert($_ASring, "String is"); $_ASring = substr($_ASring, 0, length($_ASring) -1); } [/code][/quote]
