_____________________________________________________________________

The size of the code is extended using the C code generator instead

of the TIC approach. As an example, this is the size of the EXE and

application components for a big application (using SFC and other

languages):

* with TIC code generation:

size of the TIC kernel = 180 Kb

sizeof the application TIC code = 76 Kb

Total = 256 Kb

* with C code generation

size of kernel + application linked together = 391 Kb

One explanation of this expansion is that most of the TIC codes are

more compact than the corresponding binary code. The delta is

normally somewhere in the TIC interpreter, and of course not

repeated each time the instruction is used.
