Title: [SOLVED]Are there some pre-defined variables such as __line__ like C languange ?
Post by: kinlion on December 07, 2018, 08:14:58 am

These variables are useful.
For examples:
  __build_time__ can be shown to indicate whethor the exe-file is the latest version. (The version number is not well-understood to none-programmer).
  __file__, __line__ can be used in debug out for convinent.
