 By default ECL starts up in interactive mode. Log into SDF host //miku// and type "'ecl'"; you should see something like below:

 The default ECL prompt is ">". Enter Common-Lisp commands in the usual way:
-  > (+ 1 2 3)
+<code>
-  > (* 4 5)
+> (+ 1 2 3)
-  > (format t "hello SDF~&amp;")
+> (* 4 5)
-  hello SDF
-  NIL
-  >
+> (format t "hello SDF~&amp;")
+hello SDF
+NIL
+>
+</code>
 In-line help is available ; type :h for options. The debugger can be entered using "(break)" ; once entered typed :h to see options. To exit the ECL interactive session type ":exit" .

 ex: hello.lsp
-  % echo '(format t "~&amp;Hello SDF~&amp;")' > hello.lsp
+<code>
-  % ecl -norc -script hello.lsp
+% echo '(format t "~&amp;Hello SDF~&amp;")' > hello.lsp
-  Hello SDF
+% ecl -norc -script hello.lsp
+Hello SDF
+</code>
 It's also possible to use ECL to execute simple Common-Lisp one-liners at the command line (note that //princ// is needed for screen output):
-  % ecl -norc -shell /dev/null -eval "(princ (* 1 2 3))"
+<code>
+% ecl -norc -shell /dev/null -eval "(princ (* 1 2 3))"
+
+</code>
 A nicer way to accomplish the same is to create a small shell script:
-  #!/bin/sh
+<code>
-  # lispit - executes a lisp expression and dumps it to stdout
-  LSP_EXPR=${@}
+#!/bin/sh
+# lispit - executes a lisp expression and dumps it to stdout
-  if [ "$#" -eq 0 ]; then
+LSP_EXPR=${@}
-          echo "lispit - executes a lisp expression"
-          echo "  usage: lispit '(lisp_expression)'"
-          echo ""
-          exit 1
-  fi
-  ecl -norc -shell /dev/null -eval "(princ ${LSP_EXPR} )"
+if [ "$#" -eq 0 ]; then
-  echo ""
+        echo "lispit - executes a lisp expression"
-  exit 0
+        echo "  usage: lispit '(lisp_expression)'"
+        echo ""
+        exit 1
+fi
+ecl -norc -shell /dev/null -eval "(princ ${LSP_EXPR} )"
+echo ""
+exit 0
+</code>
 Example run:
-  % lispit '(mapcar (lambda (x) (expt x 2)) `(1 2 3 4 5))'
+<code>
-  (1 4 9 16 25)
+% lispit '(mapcar (lambda (x) (expt x 2)) `(1 2 3 4 5))'
+(1 4 9 16 25)
+</code>
