I believe it's fairly simple but can't remember, or easily find in the help files, how %repeatnum and %i work, inside of nested loops.
The help for predefined variables tells me %i and repeatnum are the same, but testing tells me there are some differences.

#FORALL "a|b" {#FORALL "c|d" {#LOOP 2 {#SAY This is loop %repeatnum of %i}}}

Outputs:
This is loop 1 of a
This is loop 2 of a
This is loop 1 of a
This is loop 2 of a
This is loop 1 of b
This is loop 2 of b
This is loop 1 of b
This is loop 2 of b

Whether I use a #LOOP, #FORALL, #<number> or #REPEAT type of loop, %i seems to always return the index of the outermost loop, while %repeatnum returns the index of the innermost loop. If I have three or more loops, as in the example above, how do I manipulate them all? In this case, how do I get at the index of the #FORALL "c|d" loop?

i believe it starts at %i, then %j, %k etc etc

#LOOP 1,5 {#loop 1,2 {#show %i - %j}}

1 - 1
1 - 2
2 - 1
2 - 2
3 - 1
3 - 2
4 - 1
4 - 2
5 - 1
5 - 2

I thought it was simple. Wink

Thanks, Private.
