Does the OSS ASN.1 compiler support macros and to what degree?

The OSS ASN.1 compiler supports ASN.1 macros fully, but with the limitations as stated in the OSS ASN.1/C Compiler Reference Manual, section 9.3 (April 2011 edition), "Restrictions on the ASN.1 macro notation". For more information about macro processing, please refer to section 9 of the above referenced manual.

The samples included with some of the Knowledge Center answers are meant for your general understanding of the OSS products.
