Detailed Description

Address the Problems Caused by Incompatible Flavor of Assemblers and Toolsets.

This include file attempts to address the problems caused by incompatible flavors of assemblers and toolsets. It primarily addresses variations in the use of leading underscores on symbols and the requirement that register names be preceded by a %.

NOTE: The spacing in the use of these macros is critical to them working as advertised.
