Let me start with the questions: 1- Can I define my own event? I thought I read that in one of the hypercard books but I can't find it again ( I usually read after midnight, so I probably dreamt it up :-)). 2- Inside a XFCN (written in C) are there any special considerations regarding the use of NewHandle & DisposHandle? Could I use malloc(), or calloc()? (I still get confused by Handle stuff, specially in relation to an array of structures, with each structure containing a 2D array of strings). 3- If a have a variable Var and it contains mem1 and mem2, given by put "mem1,mem2" into Var how can I do the following, "put the value of item 1 of Var into the value of item 2 of Var" so if mem1 had "hello" to start with and mem2 was empty, after doing the line above, mem2 would contain "hello". I tried placing mem2 in target, but it didn't work. I also tried "put item 2 of Var into the target" and it didn't work. Wish List: 1- User definable events, ie. on myEvent do stuff pass myEvent end myEvent 2- Broadcast capabilities, to pass an event to other objects (buttons and fields) at the same level or higher, ie. on myEvent do stuff broadcast myEvent pass myEvent --maybe broadcast acts only at the same level end myevent 3- A way to use a more resourceful editor to write scripts. I would like to end by expressing my great admiration for the people that developed Hypercard and those that are working on improving it.

But you don't need to do this to reserve space. >how can I do the following, > "put the value of item 1 of Var into the value of item 2 of Var" > >so if mem1 had "hello" to start with and mem2 was empty, after doing the >line above, mem2 would contain "hello". I tried placing mem2 in target, but >it didn't work. I also tried "put item 2 of Var into the target" and it One way is: put item 1 of var into item 2 of var Even if item 2 didn't exist before, it will now, and if item one was 999, var will now look like 999,999 >1- User definable events, ie. > >on myEvent > do stuff > pass myEvent >end myEvent > This is already a feature. Try it by putting this handler into your background script and then "send myEvent to [whatever]", where [whatever] is some object below the background in the hierarchy (like the card or a button). Or you could just "send myEvent to background 1". -- - Scott
