ORG (Adjust Segment Location Counter)

The ORG directive sets the location counter to the value of Expression. Subsequent instructions are generated beginning at this new location.

Syntax

ORG Expression

Remarks

The assembler must know all names used in Expression on pass 1, and the value must be either absolute or in the same segment as the location counter.

The numeric value of Expression must not be a quantity larger than that which is representable by an unsigned integer having the same word size as the current segment.

You can use the current address operator ($) to refer to the current value of the location counter.

Example

ORG    120H
ORG    $+2     ;SKIP NEXT 2 BYTES

To conditionally skip to the next 256-byte boundary:

CSEG    SEGMENT    PAGE
BEGIN   =          $
        .
        .
        .
        IF ($-BEGIN) MOD 256
;IF NOT ALREADY ON 256 BYTE BOUNDARY
        ORG ($-BEGIN)+256-(($-BEGIN) MOD 256)
        ENDIF
