The CMACROS.INC file contains the assembly-language definitions for all Cmacros. You must include this file at the beginning of the assembly-language source file by using the INCLUDE directive. The line has the following form:
INCLUDE CMACROS.INC
You must give the full path if the macro file is not in the current directory or in a directory specified on the command line.
For a complete description of each of the Cmacros, see Section 14.4, “Alphabetic Reference.”
