The UNIX version is already installed on the SUN workstations networked in the Department of Mathematical Sciences, University of Durham. You can run the program by typing the command ``bd'' at the unix prompt.
We refer to the directory from which [B/D] is run as the current directory. All temporary files are placed on, and all output directed to, the current directory. The various required files must be present either in the current directory, or in the path given by the environment variable BDINPUTS . The current directory is always searched first. (The search path can be added to interactively if necessary.)
For the version of [B/D] which is set up to run over the Durham University Mathematical Sciences Department network, this variable should be set by adding the following line to your .cshrc file:
setenv BDINPUTS /usr/local/src/modsrc/BD/
The BDMACROS environment variable is set in a similar way to the BDINPUTS variable. It can be set to contain a string of paths which are to be searched for input files. For example, you might add the following line to your .cshrc file:
setenv BDMACROS $HOME:$HOME/bd/bdinputs/
For its input files, the effect here would be for [B/D] to search (by
default) the current directory first; and then the subdirectory
bd/bdinputs/, and so forth.
