- commandloop [prompt] [prompt2]
- Create an interactive command loop for the current TCL
- interpreter. This command receives commands from stdin
- and executes them. It is useful TCL scripts that do
- not normally converse interactively with a user through
- a Tcl command interpreter, but which sometimes want to
- enter this mode.
-
- Prompt is a Tcl command string that is evaluated to
- determine the text of the prompt string. Prompt2 is a
- command string that is evaluated to determine the
- ``downlevel prompt'', which is the prompt which is
- issued for continuation input. When the command
- terminates, the variables for the prompt hooks will be
- set to their old value. If these arguments are not
- specified, the prompt hooks use their current value.
- Prompt hooks are TCL code that return as their result
- the prompt to output. The result of the last command
- executed in the command string (which may be a return)
- will be used as the prompt.
