Dear Walter,
Here is a request to implement sharing of specifically marked data segments
(instead of marking the entire data sharable), similar to VC implementation.
i.e. Currently, there is no data_seg pramga in DMC. (Or is there?...)
#pragma data_seg(".shared")
int i;
char s[30];
Myclass mc;
#pragma data_seg()
Please comment.

There is currently no mechanism for naming the data segment from the
compiler.
The program patchobj, however, can rename it with:
patchobj test.obj -l_DATA _SHARED
which will rename the _DATA segment to _SHARED. You can verify this working
with obj2asm. You'll also need to segregate all the data going into _SHARED
into a separate source file.

I have 'patchobj' circa 1995, it does not support -I flag. The latest distribution does not contain a newer version. How can I obtain the proper version? Other than that, this looks like a workable solution. - Rajiv Walter <walter digitalmars.com> wrote in message news:9ah3t7$11hs$1 digitaldaemon.com...There is currently no mechanism for naming the data segment from the compiler.

"Rajiv Bhagwat" <dataflow vsnl.com> Thanks! I made a mistake in reading l_DATA as I_DATA... (The switch is ell not eye! - The two look exactly identical in Arial.) Even the old one supports that. I found out after the new one failed on 'eye' also. The results are identical and could be verified by dumpobj. Thanks again. - Rajiv Walter <walter digitalmars.com> wrote in message news:9amogd$2u9g$1 digitaldaemon.com...Attached.
