Returns the signed 64-bit value at the specified memory location as an INT64 value.

Syntax

GET-INT64 ( source , position )
source
A function or variable that returns a RAW or MEMPTR value. If source is the Unknown value (?), GET-INT64 returns the Unknown value (?).
position
An integer value greater than 0 that indicates the byte position where you want to find the information. If position is greater than the length of source, the AVM returns the Unknown value (?). If position is less than 1, the AVM generates a run-time error.

Example

The following example demonstrates how to get values in and out of RAW and MEMPTR values:

r-getint64.p 

DEFINE VARIABLE myint64  AS INT64   NO-UNDO INITIAL 7888999000.
DEFINE VARIABLE myint    AS INTEGER NO-UNDO INITIAL 2345.
DEFINE VARIABLE myraw    AS RAW     NO-UNDO.
DEFINE VARIABLE result64 AS INT64   NO-UNDO.
DEFINE VARIABLE result1  AS INTEGER NO-UNDO.
DEFINE VARIABLE mymem    AS MEMPTR  NO-UNDO.

ASSIGN
  PUT-LONG(myraw,1)  = myint
  result1            = GET-LONG(myraw,1)
  PUT-INT64(myraw,1) = myint64
  result64           = GET-INT64(myraw,1).

MESSAGE "raw version " result1 result64.

ASSIGN
  result1            = ?
  result64           = ?
  SET-SIZE(mymem)    = 40
  PUT-LONG(mymem,1)  = myint
  result1            = GET-LONG(mymem,1)
  PUT-INT64(mymem,1) = myint64
  result64           = GET-INT64(mymem,1).

MESSAGE "memptr version " result1 result64.

result1 = get-int64(mymem,1) NO-ERROR.

MESSAGE "store getint64 in int gives" ERROR-STATUS:GET-MESSAGE(1).
MESSAGE "doing put-long of in64" myint64.

PUT-LONG(mymem,1) = myint64 NO-ERROR.

MESSAGE "storeint64 with put-long gives" ERROR-STATUS:GET-MESSAGE(1). 
SET-SIZE(mymem) = 0.
