To find out what wrong I"m now trying to disassemble the os.hex file! I use the CrossView debugger supplied on the CD (just read the os.hex file as an image). So far I found a jump table for all VM-codes at address 0x394. For the call function (code 62) the entry is 0x3db6. At this address I see a construction to call the assembly routine. However, how it works I haven"t figured out -yet-. It seems R4 and R5 hold the segment and offset to be called, by pushing these on the stack and performing a RETS instruction, the call is made.
