READEXIT()
Toggle Up arrow and Down arrow as READ exit keys
------------------------------------------------------------------------------
Syntax
READEXIT([<lToggle>]) --> lCurrentState
Arguments
<lToggle> toggles the use of Up arrow and Down arrow as READ exit
keys. Specifying true (.T.) enables them as exit keys, and false (.F.)
disables them.
Returns
READEXIT() returns the current setting as a logical value.
Description
READEXIT() is an environment function that reports the current state of
Up arrow and Down arrow as keys the user can press to exit a READ from
the first or last Get object in a GetList. If the optional <lToggle>
argument is specified, Up arrow and Down arrow are either enabled or
disabled as READ exit keys. At program startup, Up arrow and Down arrow
are not enabled as READ exit keys. Normally, READ exit keys include
only Pgup, Pgdn, Esc, or Return from the last GET.
Examples
. This example shows READEXIT() enabling Up arrow and Down arrow
exit keys before a READ then resetting them after the READ
terminates:
cMyvar = SPACE(10)
lLastExit = READEXIT(.T.) // Result: Turn on exit keys
//
@ 10, 10 SAY "Enter: " GET cMyvar
READ
READEXIT(lLastExit) // Result: Restore previous setting
