X-PLOR Language

X-PLOR has a powerful command parser  that uses free-field input  and structured control statements. It can be used both interactively and in batch or background mode. When X-PLOR is started, it expects to read the X-PLOR statements from standard input (in most cases FORTRAN unit 5).
