[B/D] is currently available in three versions: for IBM PCs and compatibles running under WINDOWS or Linux , and for the SUN workstations, running under UNIX , networked in the Department of Mathematical Sciences at Durham University. The last allows the analysis of larger problems, but this is essentially the only difference between the UNIX and other versions. The graphics handling for the three versions differs slightly.
We consider separately installing the PC version, and using the UNIX version. The Linux version is under construction. In the final part of this chapter we survey briefly the [B/D] interface: how command lines are constructed, and so forth.
