In Borland C++ the following method works:
 
Normally, the C compiler creates different segment names and classes
for various parts of your program, something like:
 
  DEFAULT NAMES                               NEW NAMES
   segment                                     segment
name     class                              name     class
--------------                              --------------
CODE     _TEXT                              CODE     _TEXT
DATA     _DATA   (initialized data)         CODE     _TEXT
BSS      _BSS    (uninitialized data)       CODE     _TEXT
 
Since you can rename these default values using BC's -z command line
option (maybe also using the IDE by some weird menu option)
set both those data segment values to CODE and _TEXT and they will wind
up in the cseg.  And compile via assembly.
 
This trick at least works in the tiny and small models, other models may
require additional groups to be changed.  If you wish to place just
a specific variable in the cseg, then you must compile to assembly
and tweak the asm file manually.
 
example:
CFLAGS = -mt -zACODE -zBCODE -zTCODE -zC_TEXT -zD_TEXT -zR_TEXT
 
Borland may be correct in saying that doing this may cause problems
with overlaying, but it CAN be done.
