[Tiny-cobol-users] More debuggig options.

[Rildo P. <rpr...@ac...>]

Hi,

Well, my friends.  Now I implemented the debugger's access of "usage is
display" variables.  You can get those variables listed (with correct
size, of course) inside gdb.  You only have access to the symbols when the
program is running, so please; 
   (1) start gdb with the object name; 
   (2) put a breakpoint at "main" (with the command: b main); 
   (3) run.
Then you can display any variable, but only makes sense to play with
"display" variables, as the others will show garbage. You can use the
gdb's command "x/x VAR" to get the value of a "usage is comp" variable, or
"x/b VAR" to do the same with a COMP-3, for each 2-digit values.
I will look for ways to show the properties (like the picture, for
instance) as well, and to convert other kind of variables for working
inside gdb.

Nevertheless, I don't think this is going to be easy, because gdb is
optimized for running C/C++ and Modula programs, _not_ Cobol.  So, there
are some ideosyncrasies of Cobol that it don't know. Sorry :(

There is a test ready to run in test.code/t16.  Run it as stated above and
execute "d ARRAY" to see what's the contents of it.

regards,
