> If so, then getting rid of the hidden variables might be hard indeed.The function is named "variable". Given the variable name, this function returns the value of the variable. If there is no variable with the given name, then the "variable" function fails. This is an excellent point. It points out how an unreferenced co-expression variable could be accessed .although I still know of no technique for assigning a new value to these variables. I doubt if there is much use of this feature, but the fact that this is part of the standard argues strongly against changing the way co-expressions copy dynamic variables. ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
