PRB: A2108 Error When Using Simplified Segment Directives (148509)
The information in this article applies to:
- Microsoft Macro Assembler (MASM) 6.0
- Microsoft Macro Assembler (MASM) 6.1
- Microsoft Macro Assembler (MASM) 6.11
This article was previously published under Q148509 SYMPTOMS
When assembling code that uses simplified segment directives, the Macro
Assembler displays an error message similar to this one:
error A2108: use of register assumed to ERROR
CAUSE
This error can occur because of incorrect order of the .DATA and .CODE
directives in the assembly source code. The .DATA directive implies ASSUME
CS:ERROR. Any code that appears after the .DATA directive and attempts to
implicitly or explicitly use the CS register (such as JMP instructions or
labels) will generate this error.
RESOLUTION
Make sure that a .CODE directive and not a .DATA directive precedes your
procedure definitions and any other instructions.
STATUS
This behavior is by design.
