This chapter introduces the syntax and the semantics of the HDevelop language. It illustrates what can be entered into a parameter slot of an operator or procedure call. In the simplest case this is the name of a variable, but it might also be an arbitrary expression like sqrt(A). Besides, control structures (like loops) and the semantics of parameter passing are described.
Note that the HALCON operators themselves are not described in this chapter. For this purpose refer to the HALCON reference manual. All program examples used in this chapter can also be found in the directory %HALCONEXAMPLES%\hdevelop\Manuals\HDevelop.
