Sure. Read my previous letter - because resident programs NEVER should
by in .COM format (without header, which specifies executable requirements
for dynamic memory).

All simple. If your program doesn't requires additional memory (in
compare with data, already present in executable), just use something like
"-s32" option (this dynamic memory+stack, and 32 bytes of stack should be
minimum specified). If your program requires additional memory after start
(for example, if you eliminate from executable 62000 bytes of zeros, but
require 62000 bytes of memory for these zeros after start), specify
something like "-s62032" option (62000 bytes of dynamic memory + 32 bytes
for stack).
Of course, space for stack may (and should be?) more, than 32 bytes
(even if your code is not too recursive). This is because some BIOS calls
advertised as required at least 128-512 bytes of stack space.

There is no such thing as "caller stack" when we discuss transient
portion (which gets control, when program starts).

Not need to convert exe/sys to plain sys, especially because combo may
give additional features (like information about status) without additional
executables.
