object loop

[gusset]

i follow the advice to use the following syntax:

for each obj in collection.count
...
next obj

rather than

for i = 0 to collection.count -1
...
next i

because it is said to be quicker.

but if, with the first syntax, i stop code execution part-way through the loop, how can i examine which member of the collection the code has reached?

thanks

by the way, i know i could increment a variable. but is there some other way?

Well it would be:

for each obj in collection
...
next obj

>>how can i examine which member of the collection the code has reached<<

The properties of obj show which object in the collection is currently referenced. Are you talking about stopping execution in debug mode or exiting the loop when a condition is met?

sorry, you're right - for each obj in collection (not collection.count).

i was indeed talking about debugging, but the question is equally applicable for an exiting condition.

the answer is the .index property, which i had forgotten about completely.

why is it faster?

thanks
