Input editing functions

If the program was compiled with -DREADLINE, the following basic editing functions are available at the program prompt:

  ^A               : moves to the beginning of the line
  ^B               : moves back a single character
  ^E               : moves to the end of the line
  ^F               : moves forward a single character
  ^K               : kills from current position to the end of line
  ^P or arrow up   : moves back through history
  ^N or arrow down : moves forward through history
  ^H and DEL       : delete the previous character
  ^D               : deletes the current character
  ^L/^R            : redraw line in case it gets trashed
  ^U               : kills the entire line
  ^W               : kills last word

Furthermore you can move within the line using the arrow keys.

NOTE:

If you redirect the input for executed PROG using 'prog < infile' you MUST use the command 'set prompt,off' or 'set prompt,redirect' in the first line to avoid that the program 'hangs' at the end of the file. (-> set prompt)
