I have an idea for a new program, but it requires the program to be a TSR.
Does anyone know if Euphoria supports TSR's? I haven't found any
information in the docs so I'm asumming not. Just thought I'd ask before I
gave up completly.

According to the Causeway DOS extender docs:
"If a Causeway application needs to terminate and stay resident (TSR),
then INT 21 function 31 may be used....No value is required in DX "
I've never tried this, so I can't guarantee anything.
I don't know if this can be done using Euphoria's
dos_interrupt() or not, since dos_interrupt() switches into real mode.
You might have to issue the interrupt by calling a piece of
machine code that you poke in. (i.e. you'll be
executing the INT instruction from protected mode).
If you manage to get something working, please post it
to this list.
Thanks,

An euphoria program can't be a TSR because euphoria programs are
interpreted. It mean
that ex.exe should be running for your euphoria code to execute.
TSR are usually triggered by interrupt. So an euphoria program can trigger
a TSR using
dos_interrupt, but it can't itself be a TSR.

Thanks for clearing that up. I did try to use the INT 21 function 31, but
after the
program ended I couldn't do a mem command so I don't know if it ever worked.
