This is NOT the way > switch/case works in other popular software products! If you duplicate the [case] values (i.e. you wrote bad code), WebCat *will* execute the code in each matching block. I am unsure why returning only the first value is necessarily better; the code is badly written in the first place, and it shouldn't be the interpreter's business to infer what the programmer actually intended to happen. It is true that in C, the command 'break' will skip all remaining case branches. WebDNA is apparently implementing [switch]/[case] as if it were a series of [if] statements, rather than nested [if][else] blocks. If any software package silently ignores the second and subsequent [case] values, any code there is unreachable and effectively null. This is not a bug, as far as I am concerned.
