Abstract
Fortran is the language of choice for scientific programming. It has strengths in being easy to use and having desirable complex and double precision data types as well as the traditional floating point type. Unfortunately, it is weak in capabilities at system programming level. DECLIB is an attempt to remedy this deficiency. DECLIB provides a library of FORTRAN callable assembly language subroutines for the DE-20. These perform operations not generally available in the standard FORTRAN in areas of input/output, system information routines, magnetic tape operations, sorting, and utility routines covering certain data manipulations. Features of DECLIB include functionality, ease of use, robust error checking, and parameter type checking, which allows for both character variables and Hollerith literals. While these routines are specific to the DEC-20, the functionality and concepts are general and could be adapted to other systems.
