═══ 1. MKey ═══

Function : MKey 

Syntax : keypress=MKey(timelimit (,timewait)) 

   timelimit   The maximum time (ms) MKey() will wait for a key to be pressed, range 1-60000 (1 minute)
   timewait    Optional, the time (ms) Mkey() will pause between scanning the keyboard, range 1-1000 (1 second)
   keypress    1 (key pressed) or 0 (no key pressed)

Purpose : 

Get input from the keyboard, without the requirement for a key to be pressed. 
If there is no keyboard input within the given time, the function will return 
0. Use timewait (optional, may not exceed the value of timelimit) to reduce CPU 
usage. 

Example : 

/* Program */
timelimit=5000
timewait=25
SAY 'You have about 5 seconds to start typing your name.'
CALL CharOut '','What is your name? '
IF MKey(timelimit, timewait)=1 THEN PARSE PULL name ELSE name='unknown'
SAY
SAY 'Your name is' name

/* Output */
You have about 5 seconds to start typing your name.
What is your name?
Your name is unknown (possible)

General : This function is a part of M.DLL, an OS/2 REXX DLL which gives access 
to many, many easy-to-use, high-level user-I/O functions. It is now based on 
usage of the mouse, but it will most likely finally become a rather complete 
menu system, called "M". It will be for full-screen, text-mode only, due to OS 
limitations. 
Hold your horses : "M" is not available yet. 

I'm always interested in your wish-list items and comments, et cetera, related 
to such an application, as long as your wish (for the time being) isn't 
Windows-related : m1@uni-one.nl. M.DLL will at least be free for end-users, as 
far as I can tell now.
