A three-pass compiler with the following properties is briefly described: The last two passes scan an intermediate language produced by the preceding pass in essentially the reverse of the order in which it was generated, so

A routine has been developed which computes and prints out the symbolic derivative of an absolutely continuous elementary function of one or several variables. No use is made of list processing languages. The chain rule is applied …

A set of subroutines to allow algebraic manipulations on the IBM 7094 computer has been written using a List Processor, SLIP.
A series of four problems of increasing difficulty were solved using these routines.

The use and implementation of two new FORTRAN format conversions are discussed. These format types give the FORTRAN programmer control of input/output specifications at execution time.

It is suggested that the convergence properties of the usual Picard successive approximation scheme may be improved through use of nonlinear extrapolation techniques. A numerical example is provided.

A method for storing strings is described which uses blocks of indefinite size, and is therefore completely dynamic. Its relation to similar schemes is discussed.

This note describes some FORTRAN subroutines to facilitate handling of tape files. They allow symbolic naming or information files, without violating the casual scientific programmer's idea of simplicity. Some comments on two …
