Compare (FUN) ¶ FUNCTION Compare : UINT Function compares “MemoryBlockA” with “MemoryBlockB”. Up to “uiNumberOfBytes” will be compared. Example: abyMemoryBlockA : ARRAY [0..9] OF BYTE := 0 , 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ; abyMemoryBlockB : ARRAY [0..9] OF BYTE := 0 , 1 , 2 , 0 , 4 , 5 , 6 , 7 , 8 , 9 ; -> MEM.Compare ( ADR ( abyMemoryBlockA ), ADR ( abyMemoryBlockB ), 10 ) = 4 InOut: Scope Name Type Comment Return Compare UINT function return 0 if the blocks are identical. If they are different then function returns the first position that differ Input pMemoryBlockA POINTER TO BYTE address of MemoryBlockA pMemoryBlockB POINTER TO BYTE address of MemoryBlockB uiNumberOfBytes UINT number of bytes to compare
