All systems


For-in loop support

  • Overview: for-in loops allow for easy iterating over the contents of a container type, as well as over some primitive types (arrays, strings, sets) using a uniform syntax.
  • Notes: The basic implementation is Delphi-compatible, but in addition FPC also supports some extra functionality. This functionality is described on the page below.
  • More information: for-in_loop
