You have discovered what's known as a "local" variable. The variable is local to the handler (in this case, 'mouseUp') and doesn't persist past the end of the handler. It goes what is known as "out of scope" and no longer exists. The next time in, a new one is created, and initialized to VOID (a null value).
If you declare the variable as 'global', it will persist outside of the handler, meaning that it will always be "in scope" (as long as you specify that you're using the 'global' version. That will allow you to increment it each time through. You will also want to initialize it. The minimum solution is: on mouseUp global gIncre gIncre =gIncre + 2 put gIncre end This will add 2 to the variable each time. Saying it's in the global namespace means that any references to gIncre in that scope (in this case, the handler) will refer to the global version. NULL translates to 0, and you can get away with it, but a better solution (more correct) would be: on mouseUp global gIncre if (voidP(gIncre)) then gIncre =0 end if gIncre =gIncre + 2 put gIncre end So, the first time through it will be void and you will initialize it to 0. Effectively the same, but a bit more correct this way. - Tab At 10:23 PM 2/25/02 -0500, two two two wrote: >I have a very very basic lingo question. > >-------------- > >on mouseUp > gIncre = gIncre + 2 > put gIncre >end > > >-------------- > >I'm trying create a lingo script where every time I click on text, the >number increment.
