ORG
The ORG assembler directive sets the assembler location counter to a specified value in the
address space of the current segment.
The ORG directive must be followed by an integer constant, which is the value of the new
origin.
Synonyms
ORIGIN , .ORG
Syntax
<org_directive> => ORG <int_const>
Examples
ORG %1000 ; Sets the location counter at %1000 in the address space
of current segment
ORG LOOP ; ERROR, use an absolute constant
On encountering the ORG assembler directive, the assembler creates a new absolute seg-
ment with a name starting with $$$org . This new segment is placed in the address space
of the current segment, with origin at the specified value and alignment as 1.
Zilog recommends that segments requiring the use of ORG be declared as absolute segments
from the outset by including an ORG clause in the DEFINE directive for the segment.
SEGMENT
Specifies entry into a previously defined segment.
The SEGMENT directive must be followed by the segment identifier. The default segment is
used until the assembler encounters a SEGMENT directive. The internal assembler program
counter is reset to the previous program counter of the segment when a SEGMENT directive
is encountered. See Table 19, “Predefined Segments,” on page 213 for the names of pre-
defined segments.
Synonyms
SECTION
Syntax
<segment_directive> => SEGMENT <ident>
