Assuming you mean C structures, '01' levels can be consided to provide 
equivalent functionality (with the C 'pragma pack(1)' directive).

Note that the x86 (IA32) architecture uses a 4 byte boundary alignment.
TC does not use boundary alignment unless the 'SYNC' clause is used.

This can be an issue when reading files and calling C functions from TC.

Sorry, no documentation other the source 'pp_parser.y' 'pp_scanner.l' files.

All the preprocessor does is to include copybooks (COPY ..), reformat 
the COBOL sources to free format, remove comments, and print a listing 
if requested.
The output is used as input to the main compiler.

All is run as a single process. The preprocessor is called (see 
process_pp function), after the command line and resource files options 
are processed.

Hint, use the command line '-t' option to see all the intermediate files 
created. The preprocessor output are named '*.i'.

Hope this helps.
