My question is when it is a good idea to define global variables instead of local variables There are some variables in my move generator that originally were defined only as local variable in some procedures (I do not need their value when I am not in the procedures) I found a trick to make my program slightly faster by defining them also as global variable and not using them as local variables in part of the cases. My question is if there is a rule to know when to delete them as local variables I found that in part of my procedures using them as global varaibles make my program sligtly faster. when in another part of the procedures it makes my program slightly slower. Is there a way to know when it is faster without testing for every variable? I use visual studio 6 and I also chose optimize for speed in my project. Uri
