might you be willing to explain to me how, in ProntoScript, to declare a variable whose scope shall survive the end of the subroutine? The purpose would be to use it as a counter of how often the subroutine was invoked...

many thanks in advance for all help!

If you declare it outside the function on the page it should be fine, or define the variable in the device prontoscript..

iLoop = 0

function myLoop(){
iLoop = iLoop + 1
// you could use iLoop += iLoop (could be =+ I always get it wrong)
}

Just define it at the activity level. It will then be global to all scripts at the activity level and all scripts running on pages of that activity

a million thanks - it works nicely! Now, is there a way to make its scope truly global? Right now, the variable reinitializes every time I navigate away from that activity. I tried placing it onto the activity property of the home page, but that doesn't appear to cut it...

Have a look at System.setGlobal() and System.getGlobal() which stores/retrieves string values based on a user-defined key.

To be precise, when you leave the activity you may consider the variable destroyed as it will be when the garbage is collected. When you re-enter the activity it is re instantiated and given the initial value you provided in the code.

Lyndel's comment gives you the only other solution.
