1) No great modifications have been done for the version 3.20.

Please note that for the C generation :

- The 3.20 Workbench is fully compatible with the 3.04 target,

- The 3.04 Workbench is not compatible with the 3.20 target.

Modifications on the new target concern mainly, performance

enhancements, and bugs correction.

The C generation principle stays the same in the new version.

2) Since 3.23 release there is a new C generation possibility

called "SCC structured C"

When you select this code generator option, there will be as many

C source files and .H header files as you've got programs in your

project, plus appli.c and appli.h.

The structured C SCC can be linked only with a 3.23 target or later

version. (For example it can't be linked with a 3.20 target)

Main advantage of SCC generation is that your application code is

split into many files.

Some customers were blocked because their C compiler does not

accept large C source files.

SCC option should solve that problem.
