Subject : Compatibility in C generation
keywords: C code - SCC
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.
