ASSUME
The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.
The latest version of this topic can be found at ASSUME.
Enables error checking for register values.
Syntax
ASSUME segregister:name [[, segregister:name]]...
ASSUME dataregister:type [[, dataregister:type]]...
ASSUME register:ERROR [[, register:ERROR]]...
ASSUME [[register:]] NOTHING [[, register:NOTHING]]...
Remarks
After an ASSUME is put into effect, the assembler watches for changes to the values of the given registers. ERROR generates an error if the register is used. NOTHING removes register error checking. You can combine different kinds of assumptions in one statement.
