MemCmp()

MemCmp() compares to areas in memory (SRAM). Syntax: result = MemCmp( s1Adr as word, s2Adr as word, numBytes as word )

• s1Adr/s2Adr: Start addresses of the two memory areas (SRAM).
• numBytes: Number of bytes to compare.
• result: Integer-value of the result, meaning:
  • = 0: s1 = s2
  • > 0: s1 > s2
  • < 0: s1 < s2
