Have pondered the issue of ensuring that the OS does *not* label a seemingly-'frozen' LC app as unresponsive. The following code (which I haven't actually tried in LC, shame on me) might be helpful. Some notes after the code…
======================== local KeepMeAlive = false local NumSecs = 4 on LifeLine DerStatus case DerStatus = "on" put true into KeepMeAlive TickleMe break case DerStatus = "off" put false into KeepMeAlive break default exit to top end case end LifeLine on TickleMe if KeepMeAlive = true then send "TickleMe" to me in NumSecs seconds end TickleMe ======================== How to use this code: Put the code into your stack script, or a backscript, or wherever, as you deem appropriate. When a handler has a time-consuming chunk of code in it, do the following: LifeLine ("on") -- Time-consuming -- chunk -- of -- code LifeLine ("off") I used the case structure to provide for any future use-case in which you want more options than just "keep this thing alive" or not. NumSecs is a local variable so that it can be easily adjusted in case this code is run under an OS that thinks, say, 2 seconds is a long-enough period to justify treating an app as unresponsive. ======================== It occurs to me that if you're looking for specific strings in a Very Large File, and you're reading the VLF in N-character-long chunks, you want to be careful that you don't overlook instances of a sought-for string which have a between-chunks boundary within them. Say you're reading 1000-character chunks, and your sought-for StringX *starts* at char 999 within the VLF. In this case, only character 1 of StringX will be found within the first chunk; only characters 2 thru -1 of StringX will be found within chunk 2. If you *just* look *within* each chunk as you read it, you won't find the instance of StringX which started at character 999.
