Re: [Cobolforgcc-devel] Debug information.

Betty,

COBOL4GCC uses the GCC code generation back end for code
generation. GCC also generates the debugging information. The
program "GDB" is used as the debugger.

The compoiuler front end captures the information and passes it
to the code generation. It is then passed to the assembler as
special pseudo-ops. There are numberous formats (see the doco on
gcc -g option for details).

The GCC site has a lot of documentation on this. Have a look at
http://gcc.gnu.org.
