[REBOL] Passing arguments to a function in another script

From: warren:howsoft at: 7-Feb-2008 13:48

Hi All, Here is a script called arithfunc.r: Rebol[] sum: func [arg1 arg2] [ addem: arg1 + arg2 alert to-string addem ] ------------------------------------ In the same folder, I can successfully call the above function from another script and pass its arguments as follows: Rebol[] mylay: layout[ button [do %arithfunc.r sum arg1: 3 arg2: 2] ] view mylay ------------------------------------ Using the above, the Alert in the function correctly reports the result "5". However, I would like to set the arguments above to variables rather than citing the literals "3" and "2" as I have done above. The following, for example, DOES NOT WORK: Rebol[] mylay: layout[ firstvar: 3 secondvar: 2 button [do %arithfunc.r sum firstvar secondvar] ] view mylay ------------------------------------ Nor does this, or anything else I have tried: Rebol[] mylay: layout[ firstvar: 3 secondvar: 2 button [do %arithfunc.r sum arg1: firstvar arg2: secondvar] ] view mylay ------------------------------------ All the above demonstrates a wonderful noob confusion, how typical I don't know. I am obviously missing something! Even in the version that works (using literals and not variables to pass the arguments), I am not clear about why I need to say:- button [do %arithfunc.r sum arg1: 3 arg2: 2] - and NOT: button [do %arithfunc.r sum 3 2] Can anyone show me how to pass the arguments to the function in the other script with the use of variables? Thanks. Bob
