Server 6.6.1 and Multi-Line "put"

[Jerry Jensen]

It sure sounds like the age-old line-ending confusion, which still confuses me. Sometimes its cr, sometimes its lf, sometimes its both. Not only that, I can never remember which one results from "return".

My script will need to respond to several commands - ie., ‘help’ - by outputting several lines of information to the Terminal. I am finding, however, that Server is choking if I create text programatically that contains a ‘return’ character. Example:

I’m starting to think that maybe 6.6.1 is not the version that was used in the sample script shown in the blog - perhaps a developer preview of 7.0, which handles unicode differently, is being used, and this could account for the difference in behaviour. In any case, from my end it seems to be impossible for me to write a script like the one being shown.
