modifier

From Free Pascal wiki

English (en) Esperanto (eo) suomi (fi) français (fr)

Modifiers are keywords modifying the standard behavior of a Pascal language construct, although some modifiers merely serve the purpose of being a hint to the compiler.

declaration modifiers

allocation

routines

hint directives

If {$modeSwitch hintDirectives+}, the following hint modifiers are available too:

  • deprecated
  • experimental
  • platform
  • unimplemented

These “modifiers” actually have no effect on the generated code, but can be promoted to errors using {$warn} (so, for example, in order to ensure deprecated functionality is not used in a release version).
