Q28625: High and Low Operators on External Items

{% raw %}

Article: Q28625
Product(s): See article
Version(s): 5.10
Operating System(s): MS-DOS
Keyword(s): ENDUSER | | mspl13_masm

Problem:
   The High and Low operators are not working on my external
variables. The following source code demonstrates the problem:

   .model small
   extrn e:dword
   .data
   dd  8 dup(low e,high e)
   end

Response:
   The source code above exhibits the incorrect use of an EXTRN
statement. The EXTRN statement must be either defined within a segment
or referenced using a segment override. In the above example, the
.DATA should be placed before the EXTRN statement in order to
associate the variable "e" with a segment.
