When a Ramtek display is not available or to permit off-line plotting to a "simulated" Ramtek device, a set of routines known as the Ramtek Emulation File (REF) routines are included in LONGLIB. These routines replace the Ramtek communications routines (RAMLIB) in a version of the LONGLIB graphics library named LONGLIBR.OLB. This software emulates many (but not all) of the important functions of the Ramtek communication routines to a 9460 or 9050 Ramtek display using an internal byte array. The REF subpackage uses some VAX FORTRAN specific constructs (for efficiency) but could easily be modified for
