Is it possible for a shred to receive an float argument, from Command Line, that is the Gain of the shred and so gradually and manually faing the shred? Thanks for answering my surely stupid question!

If that's the case well then yes, programs can receive floats arguments from command line. Here's an example: // loop through all the arguments // those which are not 'floats' will be printed as 0 if(me.args()) { ??? for(0 => int c; c < me.args(); c++) ??? { ??? chout <= Std.atof(me.arg(c)) <= " "; ??? } ??? chout <= IO.nl(); } Std.atof(me.arg(0)) => float myArg; chout <= "1st argument: " <= myArg <= IO.nl(); You can launch this program and pass one or more args the following way (assuming you saved it as myScript.ck): chuck myScript:1.23:5555:thridArg where you have 3 args: 1.23, 5555, thirdArg The colon character ":" is used to separate the various arguments, with no space between them. me.arg() returns all the arguments as strings, regardless of their type (numbers, literals), so you need to convert them (when possible). Std.atof() and Std.atoi() (ASCII to Float and ASCII to Int - more info here ) will do the job, but keep in mind that when the argument passed is a 'string' that can't be properly converted into a number (ie "thirdArg"), they'll return 0. Now this is just the way you can pass arguments to a program, then you'll have to implement a way to make it fade out. The only thing that is not clear to me yet, is how you want to use this to actually fade out and terminate a program, considering the arguments are passed when the program is launched. But anyway, let me know if you have any questions, and/or if I can be of any help.
