Abstract: The invention relates to a method for the translation of a sub-programme (2) by an interpreter (5) in a control device (4) for the control of a machine tool, production machine and/or a robot, whereby the sub-programme (2) comprises a number of process blocks which are serially read by the interpreter (5). On reading a process block by the interpreter (5), defined as a pattern instruction by graphical information and containing structure information on the data format of subsequent process blocks, a form (8), comprising said data format is generated by the interpreter (5) and stored and the parameters for a process block subsequently read by the interpreter (5) are entered on the form (8) and, similarly, a data set (9) is generated from the form (8) and the parameters of the process block. The invention relates to a corresponding control device.
