HB_SETKEYSAVE()

Returns a copy of internal set-key list, optionally overwriting

Syntax

HB_SETKEYSAVE( [ <OldKeys> ] )

Arguments

<OldKeys> is an optional set-key list from a previous call to HB_SetKeySave(), or NIL to clear current set-key list

Returns

Current set-key list

Description

HB_SetKeySave() is designed to act like the set() function which returns the current state of an environment setting, and optionally assigning a new value. In this case, the "environment setting" is the internal set-key list, and the optional new value is either a value returned from a previous call to SetKeySave() - to restore that list, or the value of NIL to clear the current list.

     local aKeys := HB_SetKeySave( NIL )  // removes all current set=keys
     ... // some other processing
     HB_SetKeySave( aKeys )
Tests
     None definable
