A „Self-Operation“ stand for themselves and aren't provided for the use within expressions. „Variable“ in the description means variables in the working memory (SRAM). These were dimensioned as an array, element of a structure or property of a user-defined class.

This operator-combination is used to increment a variable value (addition of 1).
See also: Incr, Decr
variable++
Example:

  dim a as byte
  dim b(3) as word
  dim x as integer
  a++
  b(3)++
  x++

This combination operator is used to decrement a variable value (subtraction of 1).

variable++
Example:

  dim a as byte
  dim b(3) as word
  dim x as integer
  a--
  b(3)--
  x--

This combination operator is used to add the variable value with the given expression value.
variable += Expression
Example:

  dim a as byte
  a += 10  ' like a = a + 10

This combination operator is used to subtract the the given expression value from the variable value.
variable -= Expression
Example:

  dim a as byte
  a -= 10  ' like a = a - 10

This combination operator is used to multiply the variable value with the given expression value.
variable *= Expression
Example:

  dim a as byte
  a *= 10  ' like a = a * 10

This combination operator is used to divide the variable value with the given expression value.
variable /= Expression
Example:

  dim a as byte
  a /= 10  ' like a = a / 10
