- Installation and Start-Up Procedure
- for J, Version 4.1, on personal systems
-
- 0. This distribution consists of two compressed tape archive files:
-
- tutorials.zoo Tutorials.
- j_4.1_XX.zoo The executable.
-
- 1. These installation steps are suggested:
-
- mkdir ~\j Create a new directory called "j".
- mv *.zoo ~\j Move the two '.zoo' files to the new directory.
- cd ~\j Change to the new directory.
- zoo -e *.zoo Expand the compressed '.zoo' files.
- rm *.zoo Remove the '.zoo' files. Alternatively,
- move them to some safe place.
- mv j_* j.tos Rename the executable.
-
- 2. If yours is a one user system, these steps are suggested:
-
- alias j "~\j\j.tos" Set an alias for j. You probably want
- this line in your ".cshrc" or "aliases" file.
- j To start the program. (Use CTRL D to end.)
-
- With this setup, J will be available to you from any directory.
- The J tutorial will be available to you whenever you make "~\j"
- your current directory.
-
- 3. When you start J, you should soon see the message
-
- J Version 4.1 Copyright (c) 1990-1992, Iverson Software Inc.
-
- and a 3-space prompt. At this point, the system is ready to
- interpret J sentences. To terminate the session, enter ^D (Control D) .
-
- 4. A tutorial is available. Within a J session, enter:
-
- 0!:3 < 'tutorial.js' Make the necessary definitions
- tutorial '' Start the tutorial
-
- 5. The directory used for the binary file "j.tos" may be changed,
- depending on the conventions in use at your installation. Some system
- administrators may like J itself to be installed as "\bin\j".
- The J tutorial files may be installed in a different directory,
- such as "\software\j\doc". If this directory path is used, the
- files needed by the tutorial would be named:
-
- \software\j\doc\tutorial.js
- \software\j\doc\tut\tut*.js (47 of these, numbered 0 to 46)
-
- In such a setting, for the file "tutorial.js" to run correctly, it must
- be modified. In this file, the line
-
- frames=.<&read ('tut\tut'&,)&(,&'.js')&":&.>i.47
-
- may be replaced by
-
- Path =. '\software\j\doc\tut'
- frames=.<&read ((Path,'\tut')&,)&(,&'.js')&":&.>i.47
-
- Then users may be instructed to do these steps,
-
- % cp \software\j\doc\tut\tutorial.js .
- % j
-
- 0:!3 < 'tutorial.js'
- tutorial ''
-
- Or users may be instructed to do these steps:
-
- % j
-
- 0:!3 '\software\j\doc\tutorial.js'
- tutorial ''
-
- 6. Some first time users have found it useful to print the 47
- tutorial files (about 20 to 30 lines each) and have them at hand
- while experimenting with the system.
