    _______________________________________________________


I am not sure if it is a bug, but I think it would be better if the
"feature"
below is modified.

As one knows, it takes quite a few compiles to get a spad file in the right
form, especially when one is learning. I also like to keep a record of the
mistakes I made as well as to document any possible bugs. So what I want to
do
is this:

)spool mytest.output
)sys cat mytest.spad
)comp mytest.spad
-- go make some changes
-- repeat the previous two commands
)spool

At the console the file is displayed. However, spool does not capture any
output
from the )sys cat command.

I lost all the changes I made to mytest.spad even though eventually, I got
it
working.

My request therefore: Is it difficult to modify spool so it will also
capture
all the output from a system command like cat? (I don't expect spool to
capture
other than "terminal" type output streams.)

William
