ASN1C90

---

The ASN1C90 version of the compiler is a separate executable that contains extensions to handle the older 1990 version of ASN.1. Although this version is no longer supported by the ITU-T, it is still in use today.

This version of the compiler also contains logic to parse some common MACRO definitions that are still in widespread use despite the fact that MACRO syntax was retired with this version of the standard. The types of MACRO definitions that are supported are ROSE OPERATION and ERROR and SNMP OBJECT-TYPE.
