PeekByte

ByteValue = PeekByte(Address)

Parameters:     Address = The Address in memory where this data should be read

Returns:     ByteValue = The byte value that was read

The PeekByte function will read a byte directly from memory. FACTS:       * You can peek any memory location.       * Care must be taken when reading directly from memory. Attempting to access memory that is not part of your program will most likely cause your program to crash.       * Also See Pointer Mini Tutorial:       This example creates a bank, grabs this banks memory address (the address of the first byte in memory), pokes various test values and strings into memory, then finally reads them back.       ; Create Bank #1 and allocate 100 bytes of system memory for it   CreateBank 1,100    ; Grab the actual address (the pointer) of this banks memory.   Address=GetBankPtr(1)    ; Once you have the address of something in memory, you can now ; directly read/write information in it.    ; While this gives the user great freedom, it also means you can ; crash your program if your not careful.       ; Poke the 8bit byte value 255 into memory   PokeByte Address,255    ; Poke the 16bit Word value 64000 into memory   PokeWord Address+1,64000    ; Poke the 32bit INteger value $aabbccdd into memory   PokeInt Address+3,$aabbccdd    ; Poke the 32bit Floating Point value 123.456 into memory   PokeFloat Address+7, 123.456       ; Poke the a null terminated string "Hello World" into memory   PokeString Address+12, "Hello World",0          ; Peek and display our byte from memory   Print PeekByte(Address)    ; Peek and display our word from memory   Print PeekWord(Address+1)    ; Peek and display our Integer value from memory   Print Hex$(PeekInt(Address+3))    ; Peek and display our Floating Point value from memory   Print PeekFloat(Address+7)    ; Peek and display our null terminated string from memory   Print PeekString(Address+12,0)       ; Display the Screen and wait for the user to press a key   Sync   WaitKey       This example would output.      255   64000   $aabbccdd   123.456   Hellow World
