1GENERAL: ask - ask for interactive input from within a macro

Usage: ask <prompt> <variable> {<variable>}

The statement "ask" writes the string <prompt> to standard output, reads 
one line from standard input, and assigns strings separated by blanks to
the variables. The command is usually used within macros.

Example: ask "First and last point:" first last
         First and last point:
         12 45
         print Range=$first...$last.
         Range=12...45.
