[open-cobol-list] question about linkage section variables

Subject: question about linkage section variables
--------

With the current compiler, linkage section records that
are not passed as usage parameters, are initialized
to NULL pointers at the beginning of the module, for
example
        unsigned char *b_1152 = NULL;

However, this initialization takes place each time
that the module is invoked.


With the MVS compiler, values assigned to these variables
are persistent.  I changed this to use
        static unsigned char *b_1152 = NULL;
instead to work around the problem.

I am not familiar with Cobol semantics.  Which is correct?
