MemFree 0.91



This app is copyright ) 1993 Matthew Dixon Cowles. It is free. Please use it if you like and use ideas and code from it in your own apps, but if it is distributed substantially complete, only a nominal download or duplication fee may be charged.



As usual, this app appears to work for me. That does not mean that it is bug-free. Use it at your own risk. No warranties are expressed, implied, or even hinted at.



MemFree shows the amount of memory free as reported by stats() -- that is, the amount of the NewtonScript heap that's free. The number is kept up to date by a viewIdleScript (as long as the checkbox is checked) and the GC button can be used to force a garbage collection if you want to know the amount of memory that can be made free. It's (in my opinion) a mildly annoying aspect of stats() that it prints more information in the inspector window than it returns as a call. For that reason, if you have the inspector open while MemFree is running, you will get the output of the stats() call every 3 seconds. I would cheerfully turn this aspect of stats() off if I knew how, but I'm not at all sure that it's possible. For that reason, in this version, it's possible to turn off the viewIdleScript by unchecking the checkbox. At any time the current number displayed can be brought up to date by tapping on it. In any case, the app saves me some typing and so I'll live with it.



Since MemFree is implemented as a floater, it should cause a minimum of interference with any other app being run. It can be dragged by its edges so as not to obscure other interesting things on the screen.



The primary advantage of version 0.91 is that (in addition to the ability to turn off the viewIdleScript) it should work correctly on an MP110. The return value of formattedNumberStr(x,"%.0f") was changed in the 110's ROMS and this version should work correctly on both machines.
