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.
