RESTORE
Retrieve memory variables from a memory (.mem) file
------------------------------------------------------------------------------
Syntax
RESTORE FROM <xcMemFile> [ADDITIVE]
Arguments
<xcMemFile> is the memory (.mem) file to load from disk. If an
extension is not specified, the extension .mem is assumed. The file
name may be specified as a literal string or as a character expression
enclosed in parentheses.
ADDITIVE causes memory variables loaded from the memory file to be
added to the existing pool of memory variables.
Description
RESTORE is a memory variable command that recreates public and private
variables previously SAVEd to a memory (.mem) file and initializes them
with their former values. The scope of the variable is not SAVEd with
the variable, but is instead established when the variable is RESTOREd.
Arrays and local variables cannot be SAVEd or RESTOREd.
When memory variables are RESTOREd, they are recreated as private
variables with the scope of the current procedure or user-defined
function unless they exist as public variables and you specify the
ADDITIVE clause. If ADDITIVE is specified, public and private variables
with the same names are overwritten unless hidden with PRIVATE. If
ADDITIVE is not specified, all public and private variables are released
before the memory file is loaded.
Local and static variables are unaffected by RESTORE. If a local or
static variable has been declared in the current procedure or user-
defined function and a variable with the same name is RESTOREd, only the
local or static variable is visible unless references to the RESTOREd
variable are prefaced with the MEMVAR alias.
Examples
. This example demonstrates a typical application of SAVE and
RESTORE. Here memory variables containing screens are SAVEd TO and
RESTOREd FROM memory files:
// Create and use a pseudoarray of screens
SAVE SCREEN TO cScreen1
SAVE ALL LIKE cScreen* TO Screens
//
<statements>...
//
RESTORE FROM Screens ADDITIVE
nNumber = "1"
RESTORE SCREEN FROM ("cScreen" + nNumber)
