438 $result = showmessage($message, 'PressEnter');
440 Shows a message and optionally gets a response from the user.
442 The first two arguments, the message and the response type,
443 are mandatory. The message must be the actual string to
444 display; the caller is responsible for calling getmessage if
447 The response type must be one of "none", "yn", "free",
448 "numerical", "email", "PressEnter", or a string consisting
449 of "restrictchar " followed by a list of allowed characters
450 (space can be specified). (Case is not significant, but case is
451 significant in the list of allowed characters.) If a response
452 type other than the above-listed is specified, the result is
455 Note that the response type "yn" is equivalent to "restrictchar yn".
456 Because "restrictchar" is case-sensitive, the user is expected
457 to enter "y" or "n" in lowercase only.
459 Note that the response type of "email" does not actually
460 guarantee that the returned value is a well-formed RFC-822
461 email address, nor does it accept all well-formed RFC-822 email
462 addresses. What it does is to restrict the returned value to a
463 string that is looks reasonably likely to be an email address
464 in the "real world", given the premise that the user is trying
465 to enter a real email address.
467 If a response type other than "none" or "PressEnter" is
468 specified, a third argument, specifying the default value, can
469 be specified: If this default response is not specified, the
470 default response is the first allowed character if the response
471 type is "restrictchar", otherwise the default response is the
472 empty string. This default response is used when the user does
473 not specify a value (i.e., presses Enter without typing in
474 anything), showmessage will assume that the default response is
477 Note that because the response type "yn" is equivalent to
478 "restrictchar yn", the default value for response type "yn",
479 if unspecified, is "y".
481 The screen is normally cleared before the message is displayed;
482 if a fourth argument is specified and is nonzero, this
483 screen-clearing is not done.
