Hacker’s Guide to Visual FoxPro
An irreverent look at how Visual FoxPro really works. Tells you the inside scoop on every command, function, property, event and method of Visual FoxPro.
READKEY()
We didn’t use this function much in FoxPro 2.x. We don’t use it at all in Visual FoxPro. It tells you how the last READ or full-screen editing command was exited.
Usage
nCode = READKEY( [ nReadOnly ] )
The optional parameter tells READKEY() to pay attention only to the last READ and indicate the cause for its death. Otherwise, the function returns information about the last full-screen editing command that ended—this includes Browse, Append, Read and a few others.
See Help for the list of codes returned if you have to maintain old code that includes this function. Don’t write any new code using it.
