- I created a program (using DISKSAVE) which reads from standard input and
- writes to standard output. The problem is that I want to differentiate between
- two sorts of output. The first one is the program output which can be
- directed to a file (i.e. under unix: % myprogram < input > output). The other
- type include messages concerning the progress of the program which should
- appear on the screen.
-
- In LCL4.0 *standard-output* stream is equal to *error-output*. So the output
- directed through any of these will make no difference. Even *terminal-io* is
- the same. I don't want to direct the error output (or progress messages) to
- a file because it is important for the user to see.
-
- Another question: is there a way to decrease the size of the program (Lisp Image)?
-
- Thank you in advance for your help.
