The information in this article applies to:

  • Microsoft Macro Assembler for MS-DOS, version 5.1

SYMPTOMS

The SUBSTR assignment to A in the following program should not be different than the SUBSTR assignment to B: 

    .MODEL SMALL
    .CODE
A   equ    <abcdef>
B substr A,4 A substr A,4 
    END
In this program, the assignment to B is "abcdef". The assignment to A is "def".
