twinBASIC Constants

trueBASIC has many built-in constants. Using constants, gives the developer a readable value that is easy to understand. Without constants, many properties would require integers to be used to represent the various states, making the code harder to write and understand later.

Appearance

  • vbAppear3d = 1

Alignment

  • vbLeftJustify = 0 - Left align data in the control
  • vbRightJustify = 1 - Right align data in the control
  • vbCenter = 2 - Center data in the control

Character

  • vbBack = Chr(8) (Backspace character)
  • vbCr = Chr(13) (Carriage return character)
  • vbCrLf = Chr(13) + Chr(10) (Carriage return + linefeed combination)
  • vbLf = Chr(10) (Linefeed character)
  • vbNewLine = Platform-specific new line character
