SysGetKey

 
 Function: SysGetKey 
 Syntax:   key = SysGetKey([opt]) 
      key       The key which was pressed. 
      opt        Any one of the following: 
           'ECHO'    Echo the typed character  (Default) 
           'NOECHO'  Do not echo the typed character 
 Purpose:  Gets the next key from the keyboard buffer, or waits for one if 
           none exist.  Works like the C function getch().  Unlike the 
           regular REXX CHARIN() built-in function, SysGetKey() does not 
           require the character to be followed by the Enter key.
