You would have to use a Global Variable 
Either through Namespaces or Through Registry. 
Example 
set *Mwinc_Pause #True
wait 1200 ; 1 Minute 
set *Mwinc_Pause #False ; Sets the Global Variable back to False
halt
Then in your other scripts you would add this line to its cycle
if *Mwinc_Pause = #True 
Pause
