  • Statements
  • Variables (var)
  • Constants (const)
  • Name spaces (namespace)
  • Direct access to memory (pointers, directive absolute)
  • Compiler directives: IFDEF, ENDIF, DEFINE, ...
  • Operators (and, or, xor, not, shl, shr, +, -, /, *, div, mod, as, in, ...)
  • Expressions (parenthesis, operator priority, infix notation)
  • Assignment (:=)
  • Function overloading (overload)
  • Integrated assembler (asm-end)
  • Subroutines (function, procedure)
    • Nested functions
    • Functions parameters
