Appendix D. Cg Keywords

D.1 Cg Keyword List

Following is the list of Cg reserved words. Words marked with an asterisk are case-insensitive.

In addition to the words on this list, any identifier with two underscores as a prefix (for example, __ newType ) is reserved. Note that matrix and vector types (such as half2x3 or float4 ) are not on this list because they can be used as identifiers. Still, we recommend that you treat the matrix and vector types as reserved words, thereby avoiding confusion.
