  GETS

  .  Summary

  gets(str <buffer>, int <max>);

  .  Description

  The gets function allows the user to enter a complete string, and
  use the arrow keys to edit it while it is being entered. <buffer> is
  the string variable where the string should be put, while <max> is
  the maximum number of characters the user may enter (from 0 to 80).
  The user may edit the string as it is being entered, with the Left-
  Arrow, Right-Arrow, Ctrl-Left-Arrow, and Ctrl-Right-Arrow keys as it
  is being entered, and insert mode may be toggled on/off with the INS
  key. String entry is over when the user presses Enter (Carriage Re-
  turn on some computers). The user may press Esc to abort string en-
  try, in which case the resulting string will have a length of 0.

  .  Return Value

  The number of characters entered by the user are returned. If the
  user pressed Esc to abort string entry, a value of -1 is returned.

  .  Example

  int n;
  str password[8];
  printsc("Enter a password? ");
  n = gets(password, 8);
