>From memory that is how they code most (all?) while/for loops. They place a
jump at the top of the code (or duplicate the first test condition at the
top) to the actual test which occurs at the end of the loop, so they can
then do a conditional jump to the top of the loop while the continue
condition is true ...
Makes sense when writing assembler code ...
- Seems like the IDE/Debugger actually put the breakpoint in the wrong place
...
I had a worse one the other week - the debugger went into an infinite loop
(not the first time I had this problem) on the second pass through the loop.
When not run under the debugger all was fine ... Go figure that one - (gave
me a headache ...)
I gave up and re-write the code so I could debug the portion I wanted to
view ..
