7 System Programming

7-1 EMS SSN/4.4
Error Message Service

EMS is a set of low-level routines which implement the facilities required by the ERR and MSG routines (see SUN/104). This separate interface to the lower levels is provided for those writing system software which does not require the ability to interact with a user, but simply needs to report and manage error messages. In particular, EMS should be used in preference to ERR/MSG by those developing ADAM system software residing in, or beneath, the parameter system.

7-2 CNF & F77 SGP/5.1
Mixed Language Programming

Provides advice, routines and macros to help you pass information between code written in Fortran 77 and C (in both directions) in a machine-independent way.
