[fpc-devel] Some thoughts on multi-line string support, and a possible syntax that I think is perfectly clean and Pascal-ish.

Ah! Check the location of the error. It's the Writeln, not the

handle this case. But to be fair it's really seldom that someone uses $H 
locally, so that's not really a tested situation...
