I am using Josh's 8080A CPU board and downloaded MBASIC-80 REV 5.21. I am not having any issues and I don't get errors when I use the immediate mode. I am also using BASCOM and L80 to compile the BASIC programs. I am guessing that the error occurred when downloading MBASIC. Try going back to the website where you found MBASIC and download again. I found that Josh's XMODEM doesn't work very well above 32K,and make sure you have enough blocks allocated when you save the program.
