Note on "the design of a user interface to large Fortran subroutine packages under IBM 360/370 OS"
James M. Boyle · ACM SIGNUM Newsletter · 1975
The article by Tweedale and Chan in the Jan. 75 SIGNUM Newsletter mentions the control program supplied with EISPACK without giving a suitable reference. Unfortunately, they seem not to be aware that its design and operation, and the philosophy behind them, are thoroughly documented in [1]. In particular, [1] discusses programming techniques which simplify the interpretation of the arguments and the selection of subroutines to perform the computation.
