This tutorial is to explain how to use the Tektronix 4115B with the VAX as host. Section I explains the method of logging in, while section II describes the library facilities available. Section III describes the basic program format to use and Section tV tells how to compile a C program so that it includes the library routines. The Appendix contains the librarv routines and some examples of C programs written especially for the Tektronix 41158.
