Problem with with the SPL system command

I've tried the SPL "system" command. Executing a procedure containing such a statement, results in Error code -668 and -1. I've checked the file permission on the operating system commands which I have tried to execute and they are executable files. (Other types of SPL commands seems to work properly). Any help would be greatly appreciated. patrik -- ----------------------------------------------------------------------- |COOL PEOPLE WEAR | Patrik Johansson |DARK GLASSES | System Administrator | University of Skoevde |____Calvin&Hobbes______________________________________________________
