15 Ú ÖÖÓÖ ÚÖ defines an error variable, i.e. a variable which contains the status of the last call of an operator. ÖÖÓÖÎÖ will be H MSG TRUE (2) if no error had occured. The parameter ÅÓ specifies if the error variable should be used (1) or not (0). If an error variable is active it will be updated each an operator excetion is finished. Thus a value is only valid until the next call of an operator. The value can be saved by assigning it to another variable (see example) or by calling Ú ÖÖÓÖ ÚÖ´ÖÖÓÖÎÖ¸¼µ. Attention If Ú ÖÖÓÖ ÚÖ should be used for exported Code (C++), please note the different handling of return values in C++. Parameter º ÖÖÓÖÎÖ (input control) ....................................integer(-array) integer Name of the variable which shall contain the error status. º ÅÓ (input control) ...............................................integer integer Switch the error variable on or off. Default Value : 1 Value List : ÅÓ ¾0, 1 Example ÚÐÓ×ÛÒÓÛ ´µ ÚÓÔÒÛÒÓÛ ´¼¸ ¼¸ ½¾¸ ½¾¸ ³Ð³¸ ÏÒÓÛÀÒÐµ ÚÖÖÓÖÚÖ ´ÖÖÓÖ¸ ½µ Ú×Ø ´³ÚÖÖÓÖ³µ ÐÆÑ ³ÛÖÓÒÒÑ³ ÖÑ ´ÁÑ¸ ÐÆÑµ ÊÖÖÓÖ ÖÖÓÖ ´ÊÖÖÓÖ ÀÅËÌÊÍµ ÛÖØ×ØÖÒ ´ÏÒÓÛÀÒÐ¸ ³ÛÖÓÒ Ð ÒÑ ³·ÐÆÑµ Ò Result Ú ÖÖÓÖ ÚÖ always returns 2 (H MSG TRUE) Parallelization Information Ú ÖÖÓÖ ÚÖ is local and processed completely exclusively without parallelization.

16 APPENDIX B. DEVELOP Ú Ò×ÔØ ØÖÐ opens a dialog to check the contents of a control variable. This dialog has a scrolled list with all the values of the variable. In the case of an frame grabber handle a specific dialog is opened which displays the most important frame grabber parameters and can be used to switch the frame grabber only interactively. The contents of the dilaog will be updated whenever the value(s) of variable changes. The update mode can influenced by the operator Ú ÙÔØ ÚÖ. The dialog can be closed by pressing the ÐÓ×-button or by calling Ú ÐÓ× Ò×ÔØ ØÖÐ. Attention This operator is not supported for exported C++ code. Parameter º ÎÖÐ (input control) .......................integer(-array) integer /real/string Name of the variable to be checked.
