I tried again with success (under 8.0). Thanks, all!

The Channel Math GX does accept strings inside the expression, and this works for me: C0=x>0?"a":"zzz", where C0 is a string channel, which is then filled with "a" or "zzz". I did not need to pre-fill the output channel though, but maybe this is something that works in my version (8.2, yet to be released). Check with the help desk and they can confirm if it works in 8.1. Brian's suggestion should certainly work.

I expect I misunderstand Brian, or I'm doing something wrong. But if I create string channels named "aaa" and "bbb" (names are not important), then fill "aaa" with "a" and "bbb" with "b", I can use these as the result of an expression in the "class" channel like this: =x>0?aaa:bbb This gives me "a" (the contents of the "aaa" channel) wherever the "x" channel is greater than 0, and "b" wherever "x" is less than or equal to 0. I hope this helps.

If the channel is empty, then nothing will populate. So if you create a string channel, copy the contents from another channel that is fully populated to that new string channel, then run your expression in the channel math GX, it should populate. -Brian J.
