Several of the for loops in my projects are generating a compiler warning
stating "statement with no effect". But the statements all have effects and
behave as intended. For instance:
for (r = [addRowsField intValue]; r--; r == 0)
[self createNewPoint];
This statement works exactly as you would expect. The variable r starts
with the number in a field, decrements with each loop, and stops when r
reaches zero.
Anyone else seen this? What's the cure?
Jonathan
