Eugene,

Linkage Section is used to reference data areas residing outside your
program; since these areas are not really in your program, there is really
no limit.

COBOL for OS/390 & VM will impose the following limits to COBOL programmer:

        999,999 lines of code
        16M for 01-levels
        128M for Working-storage size
        128M for Linkage section size

The 32K limit on commareas are strictly a CICS thing.

Hi Paul:

I'm not sure why this question has tilted towards the COMMAREA size in the
Linkage Section but Sergio's question was "Anybody know if have limit of
size in the Linkage Section of Cobol ? If yes, what are the size ?".

We have a system developed under CICS that has a 16 MB Working-Storage in
the main program and is accessed by other called programs in the Linkage
Section.  The COMMAREA limit is 32KB but I don't believe that this was
Sergio's question.

Regards,
Gene

Hi,

For practical purposes there's a 32K limit in CICS for the commarea even if
it's only a 32bit address pointer in the linkage section that references
something larger.  Sometimes I've run into programs that mix their CICS and
batch type processing so the commarea overlaps or is immediately adjacent to
another area and the entire thing gets passed on a call.

I know it's ugly but it happens.  Last time I saw it was 1998 doing a y2k
macro to command level conversion in assembler.
