The user must have a suitable computer(VAX or similar) available. Training in the programme language and in network generation is recommended.Commercial versions of SAINT are available which run on personal computers (MicroSAINT) Macintosh®computers, or the VAX family of computers (SAINT PLUS).NATO UNCLASSIFIED-96 -
