I need to be able to store a reference to a function so that I can call it later. Here's the situation. I have a routine (function-orig) that normally calls function-1. However, sometimes it will call function-2 and I want that sometime to be determined from outside this function. I also want this outside process to be able to have it call function-n if it wants. My approach was to have function-orig call a global variable that would normally point to function-1. If I wanted function-origto run a different function I could set the global variable with a reference to a different function. Obviously this didn't work or I wouldn't be asking the question. The only way I could make it work was to set the global variable to a string andthen do an eval on that when I want to run the function. This will work, but it seems ugly. Are there any more elegant solutions out there?

Thanks,
Nate Baxley

What's wrong with assigning just "1" or "2" to the variable you describe, then when it comes time to call the function, either
eval( "function-"+funcvar+"()" ) ;
or something like
if( funcvar == 1 ){
function-1() ;
}
else{
function-2() ;
}
