Compiler

Compiler directives instruct the compiler to perform certain tasks while a procedure is being compiled into object code. Compiler commands are not used during the execution of the procedure.

Command	Description
; (semicolon)	Delimits a new line (allows multiple commands to appear on the same line).
$INSERT statement	Inserts source code from another procedure into the current procedure at this point. The default location for the storage of BASIC+ source code is the SYSPROCS table.
, !, /...*/	Designates that the following string is a comment, and not an executable part of the code.
Begin Condition \ Pre: \ Post: \ End Condition	Begins the contract block. This block is ended with an End Condition statement, and before that, you must have at least Pre: and Post: statements.
Compile statement	Begins a stored procedure declaration (optional). One of two types of stored procedure must be specified: Function, or Subroutine.
Declare statement	Causes the compiler to recognize calls to subroutines or user-defined functions.
End statement	If not part of a multi-line statement (such as If … Then), tells the compiler to stop compilation at that point.
Equate or Equ statement	Establishes equivalency between a constant and a value, or between a constant and an expression (example: Equate BEEP$ To Char(7)).
Function statement	Directs the compiler to tag the object code of a procedure as being a user-defined function.
LineMark	Inserts a linemark character into the compiled code of code compiled without linemarks.
Subroutine statement	Directs the compiler to tag the object code of a procedure as being an external subroutine. An external subroutine does not return a value.
