Started programming in the new assembler.... it didn't go very fast. One of the reasons was, that there were still some bugs in the assembler and simulator. Also I made some changes in the instruction set because some features were missing, like a bit test instruction (TSTB). The CL, DL and DH registers were given more functions, at the cost of functions for the X and Y registers.

Floating point number entry was more difficult than floating point multiply....

All files are now updated to the newest version. You can paste the CALC_4.TXT into the simulator to see the floating point number entry, add, sub and multiply.

Next thing that I will do, is make LOG and 10^x functions. (I will use the method of An Wang, inventor of the LOCI calculator).
