READEXIT()
Toggle Uparrow and Dnarrow as READ exit keys
------------------------------------------------------------------------------
Syntax
READEXIT([<lToggle>]) --> lCurrentState
Arguments
<lToggle> toggles the use of Uparrow and Dnarrow 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
Uparrow and Dnarrow 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, Uparrow and Dnarrow are either enabled or
disabled as READ exit keys. At program startup, Uparrow and Dnarrow 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 Uparrow and Dnarrow
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
