Olav Olav 05 Jul 2008 Hi, I have this PBCC 4.04 program, which trigger error "Illegal function call", if the 3 conditions below is met. 1:Run from the commandline prompt. 2:A parameter contains a none english letter 3:And the CONSOLE SET VIRTUAL 26,81 statement is executed. (No problem if the same commandline is entered into the commandline box, and the program run from within the IDE). I should add that the commandline is pretty short(33 characters) Using WIN/XP SP3. Anyone any view on this?
