STACKS--Notes

Default settings

The default settings for the STACKS command are as follows:

Computer                              Stacks
--------------------------------------------
IBM PC, IBM PC/XT, IBM PC-Portable     0,0
Other                                  9,128

Special cases for stack allocation

Upon receiving a hardware interrupt, MS-DOS allocates one stack from the    
specified number of stacks. When you specify 0 for the n and s values,
MS-DOS allocates no stacks. If the values are 0, each running program must
have enough stack space to accommodate the computer's hardware interrupt
drivers. Many computers operate correctly, saving some memory for programs,
with n and s values of 0. If, however, your computer becomes unstable when
you set these values to 0, return to the default values.

Increasing the value of STACKS

If the STACKS values are not equal to 0,0 and you see a "Stack Overflow" or
"Exception error 12" message, increase the number or size of the stacks.
