The primary use of H2INC is to convert data automatically from C format into MASM format. This section shows how H2INC converts constants, variables, pointers, and other C data structures to definitions recognizable to MASM.
Since the names of the items translated by H2INC may be distinguished only by the case of the names, you should specify OPTION CASEMAP:NONE in any MASM files that include .INC files generated with H2INC.
