Filename: LMARFC02.DOC Project: Template: MSGRIDA1.DOT Author: Mike Eddy Last Saved By: Launi Lockard Revision #: 24 Page: 29 of 9 Printed: 10/02/00 04:14 PM Directives 29 .ERR2 [[message]] .ERR block evaluated on every assembly pass if OPTION:SETIF2 is TRUE. .ERRB [[, message]] Generates an error if textitem is blank. .ERRDEF name [[, message]] Generates an error if name is a previously defined label, variable, or symbol. .ERRDIF[[I]] , [[, message]] Generates an error if the text items are different. If I is given, the comparison is case insensitive. .ERRE expression [[, message]] Generates an error if expression is false (0). .ERRIDN[[I]] , [[, message]] Generates an error if the text items are identical. If I is given, the comparison is case insensitive. .ERRNB [[, message]] Generates an error if textitem is not blank. .ERRNDEF name [[, message]] Generates an error if name has not been defined. .ERRNZ expression [[, message]] Generates an error if expression is true (nonzero). EVEN Aligns the next variable or instruction on an even byte. .EXIT [[expression]] Generates termination code. Returns optional expression to shell. EXITM [[textitem]] Terminates expansion of the current repeat or macro block and begins assembly of the next statement outside the block. In a macro function, textitem is the value returned. EXTERN [[langtype]] name [[(altid)]] :type [[, [[langtype]] name [[(altid)]] :type]]... Defines one or more external variables, labels, or symbols called name whose type is type. The type can be ABS, which imports name as a constant. Same as EXTRN. EXTERNDEF [[langtype]] name:type [[, [[langtype]] name:type]]... Defines one or more external variables, labels, or symbols called name whose type is type. If name is defined in the module, it is treated as PUBLIC. If name is referenced in the module, it is treated as EXTERN. If name is not referenced, it is ignored. The type can be ABS, which imports name as a constant. Normally used in include files.
30 Reference EXTRN See EXTERN. .FARDATA [[name]] When used with .MODEL, starts a far data segment for initialized data (segment name FAR_DATA or name). .FARDATA? [[name]] When used with .MODEL, starts a far data segment for uninitialized data (segment name FAR_BSS or name). FOR parameter [[:REQ | :=default]] , statements ENDM Marks a block that will be repeated once for each argument, with the current argument replacing parameter on each repetition. Same as IRP. FORC parameter, statements ENDM Marks a block that will be repeated once for each character in string, with the current character replacing parameter on each repetition. Same as IRPC. [[name]] FWORD initializer [[, initializer]]... Allocates and optionally initializes 6 bytes of storage for each initializer. Also can be used as a type specifier anywhere a type is legal. GOTO macrolabel Transfers assembly to the line marked :macrolabel. GOTO is permitted only inside MACRO, FOR, FORC, REPEAT, and WHILE blocks. The label must be the only directive on the line and must be preceded by a leading colon. name GROUP segment [[, segment]]... Add the specified segments to the group called name. .IF condition1 statements [[.ELSEIF condition2 statements]] [[.ELSE statements]] .ENDIF Generates code that tests condition1 (for example, AX > 7) and executes the statements if that condition is true. If an .ELSE follows, its statements are executed if the original condition was false. Note that the conditions are evaluated at run time.
