Getting Started

Two files must be provided to run an ALPHA job:

1. A file which contains the Fortran or CVS code for the user subroutines (see Ch. 3).
2. A card file which defines the input / output data files, and allows the user to select several optional parameters (see Ch. 4).

The libraries needed to link the program are described in Appendix C. To run ALPHA, the following Fortran units must be assigned:

unit

6

Print output file

7

Card file

76

(optional): in an interactive session, this unit may be assigned to the terminal. Short messages will be sent to the terminal and long listings sent to the output file.

A command file, alpharun, described in Appendix C is available on all ALEPH computers to make these file assignments, and to perform the following tasks:

1. compile and link the Fortran (or CVS) code;
2. link with all additional needed libraries (BOS, ALEPHLIB, JULIA, MINI);
3. run the program interactively or submit a BATCH job.

On the DEC/VMS machines, alpharun also facilitates the use of a set of DEC debugger command files which simplify ALPHA program debugging.
