ARRAY and MemoryBlock ¶ Compare (Function) FindBlock (Function) FindByte (Function)

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

FindBlock (FUN) ¶ FUNCTION FindBlock : UINT Function looks for the first occurence of “MemoryBlockB” within “MemoryBlockA”. Example: abyMemoryBlockA : ARRAY [0..9] OF BYTE := 0 , 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ; abyMemoryBlockB : ARRAY [0..2] OF BYTE := 6 , 7 , 8 ; -> MEM.FindBlock ( ADR ( abyMemoryBlockA ), 10 , ADR ( abyMemoryBlockB ), 3 ) = 7 InOut: Scope Name Type Comment Return FindBlock UINT function returns 0, if “MemoryBlockB” cannot be found. Otherwise the function returns the position of the first occurence Input pMemoryBlockA POINTER TO BYTE address of MemoryBlockA uiLengthBlockA UINT length of MemoryBlockA in byte pMemoryBlockB POINTER TO BYTE address of MemoryBlockB uiLengthBlockB UINT length of MemoryBlockB in byte
