The EXEHDR and EXEMOD utilities can be used to change the stack size
of a program. EXEHDR runs in both DOS and OS/2, while EXEMOD is an
older utility that only runs under DOS.

To view the current size of the stack, no options are used. Both
EXEHDR and EXEMOD will produce a table of information with a line such
as the following:

   Initial SS:SP 0000:0800 0

The offset portion of this line gives the current stack size in hex.
In this example, the stack size is set at 2K. If you wanted to change
it to 4K, you could use the /STACK option of EXEHDR or EXEMOD in the
following way:

   EXEHDR file /STACK 1000

-or-

   EXEMOD file /STACK 1000
