The GET MEMORY STATISTICS command returns important information such as how much physical memory (RAM) is being used in addition to how much overall virtual memory the application has been allocated. Using these two values we can determine the amount of memory that has been swapped back to disk by using the following calculation:

Used Virtual Memory - Used Physical Memory = Memory Swapped to disk

The following utility method can be used to determine how much of the current applications memory has been swapped to disk:

// UTIL_HowMuchMemIsSwap // returns the amount of memory swapped to disk in bytes // $0 = C_REAL C_REAL($0) ARRAY TEXT(arrNames;0) ARRAY REAL(arrValues;0) ARRAY REAL(arrCount;0) GET MEMORY STATISTICS(1;arrNames;arrValues;arrCount) If (Size of array(arrValues)>=8)    $0:=arrValues{6}-arrValues{5} End if

If the utility method is saved as UTIL_HowMuchMemIsSwap it could be used like this:

ALERT(String(UTIL_HowMuchMemIsSwap ;"###,###,###,##0"))
