INC Variable

Increment value of Variable by one.

The INC instruction adds one from the specified variable. If the variable holds its maximum value (255 for bytes, 65535 for words), it will roll over to zero after INC.

flags           VAR     Byte(2)
result          VAR     Word

  flags(0) = 0
  INC flags(0)                                  ' flags(0) = flags(0) + 1

  result = $FFFF
  INC result                                    ' result is now $0000
