Tomasz,
What if I am using the same global in Multiple function calls?
Should they be declared global in each function? (This seems strange).
And what sort of problems can be expected from declaring globals before the
function call?
ie.
GLOBAL ResultArrayOne , ResultArrayTwo , ResultArrayThree;
Procedure SetTwoArrays()
{
ResultArrayOne = C;
ResultArrayTwo = ROC(C, 1);
}
Procedure ModResultOne()
{
ResultArrayThree = MA(ResultArrayOne,5);
}
SetTwoArrays();
WriteVal( ResultArrayOne);
WriteVal( ResultArrayTwo);
ModResultOne();
WriteVal(ResultArrayThree);
