CERNLIB overview
The CERN Program Library is a large collection of general purpose programs
maintained and offered in both source and object code form on the CERN
central computers. Most of these programs were developed at CERN and are
therefore oriented towards the needs of a physics research laboratory.
Nearly all, however, are of a general mathematical or data-handling nature,
applicable to a wide range of problems.
Contents and Organization of the Library
The library contains several thousand subroutines and complete programs
which are grouped together by logical affiliation into several hundred
program packages. 80% of the programs are written in FORTRAN and the
remainder in assembly code, or C usually with a FORTRAN version also
available. The language supported is currently Fortran 77.
Each package is assigned a unique code, consisting of a letter and
three or four digits. The letter is used to indicate the category in
which the program or package resides. A package consists of one or
more related subprograms with one package name and one or more
user-callable entry names, all described briefly in a Short
write-up , and if necessary, an additional Long write-up. The
terms under which the library material and associated documentation
may be distributed are given below.
