Introduction  The DATAPAC library was written by James Filliben of the Statistical Engineering Division. After these routines were incorporated into the Dataplot program, development of DATAPAC stopped. However, there are some subroutines here that may still be of interest. In particular, there are a number of routines for computing various probability functions. This software is not formally supported and is not being further developed. It is provided on an "as is" basis. There is no formal documentation for the subroutines. However, most of the subroutines contain usage instructions in the comments in the source code. These routines are written in Fortran 77 and should be portable to most Fortran 77 compilers. 
Contents  You can download the Fortran source code as a single file or you can download specific subroutines. The following subroutines are available:
