Design of a Command Language for Interactive or Batch Use in a Statistical Package
Jr. D. A. Henderson, David J. Wishart · COMPSTAT · 1986
The paper describes a new command language for the statistical package Clustan which is especially suitable for interactive use from a computer terminal or PC workstation. It features immediate error correction, flexible help (and more help) facilities, defaults for unspecified parameters, verification before execution, simulation of execution and simultaneous storage of commands as a program. The interactive method of operation is fully compatible with batch operation by a Clustan program.
