RE: [open-cobol-list] Status of Cobol

[Pierre Brico]

Hello Jim,

I've discovered OpenCobol a few months ago. I was searching an open source 
Cobol compiler and OpenCobol was the most developed. Keisuke has done a very 
good job ! The big advantage of OpenCobol is that it generates C code for gcc. 
That means you can compile your code on whatever machine on which gcc exists ! 
Negative side, the compilation time is longer than with a commercial compiler 
(to compile a routine of 21369 lines, OC (with maximum code optimization) needs 
10.56 sec. on Sun Fire 880. Note 95% of this time was taken by gcc itself).

Our cobol application is composed of about 3000 programs (4 million lines of 
cobol) and we use Microfocus Cobol to compile it. Unfortunately, MF has some 
extensions to cobol standards that we used without knowing. As a result many of 
the programs didn't compile due to minor causes. I modified OpenCobol in order 
to accept some of the MF specificities and now all our sources compiled and ran 
without any problem.

The only negative thing is about performances. I think there is still a lot of 
work to optimize the generated code to obtain performances as good as MF does.

Still again thanks to Keisuke.

I assume from the lack of response to my last posting that Open Cobol is
still a long way away from being a usable compiler.
