For the record (though as other commenters have pointed out, this rant on LabView is off-topic): LabView is a very successful tool that is used by many programmers in various fields, not just instrumentation. LabView does have compiler errors and syntax error highlighting; they don't look the same as in a text-focused language, but since G is a programming language, it has its own syntax and errors can occur.<p>Programming languages are an abstraction. G is just another abstraction. I've used BASIC and C compilers with terribly cryptic, useless errors too; the errors had more to do with flaws in the compiler and IDE than the language itself. If errors in LabView are cryptic or obtuse, I would assume something similar.
