GetKey
Returns the ascii code of the first key in the keyboard buffer
Syntax
`
Declare Function GetKey ( ) As Integer
`
Usage
`
result = GetKey
`
Return Value
The `Integer` value of the ascii code returned.
Description
It returns the ascii code of the first key in the keyboard buffer. The key is removed from the buffer. If no key is present, `GetKey` waits for it. For extended keys (returning two characters), the extended code is returned in the first byte, and the regular code is returned in the second byte. (see example below)
The key read is not echoed to the screen.
For a keyword not stopping the program if no key is at the buffer see `Inkey` or `MultiKey`.
Example
`
Dim As Integer foo
Do
foo = GetKey
Print "total return: " & foo
If( foo > 255 ) Then
Print "extended code: " & (foo And &hff)
Print "regular code: " & (foo Shr 8)
Else
Print "regular code: " & (foo)
End If
Print
Loop Until foo = 27
