- FILE AND DIRECTORY NAMING CONVENTIONS ON SIMTEL20
-
- SIMTEL20 is a DEC 20 host computer which runs the TOPS-20
- operating system. This file briefly describes the file and directory
- naming conventions under TOPS-20; this is not a complete description,
- but it should be enough to allow you to work with the software
- repositories on SIMTEL20.
-
-
- 1. Directory Names
- ------------------
-
- Directory names in the various software repositories on
- SIMTEL20 take the general forms of:
-
- disk:<directory_name>
- and disk:<directory_name.subdirectory_name>
-
- All software repositories reside on the disks named PD1 and
- PD2 (for Public Domain 1 and 2). Case is not signficant.
-
- Examples of directory names:
-
- PD2:<ADA> or pd2:<ada>
- -- top level of the Ada Software Repository
- PD2:<ADA.GENERAL>
- -- the GENERAL subdirectory under the ASR
-
-
- 2. File Names
- -------------
-
- File names under TOPS-20 are of the following general forms:
-
- file_name.file_type.version_number
-
- Both the file name and file type fields are not case
- sensitive. Each field can be quite long, but, as a general rule, the
- file name field is restricted to 9 characters (the first 6 are unique)
- and the file type field is restricted to 3 characters; this is to
- enhance transportability between different operating systems. The
- version number field is optional when referencing a file; if omitted,
- the latest version of the file is referenced.
-
- Examples of file names:
-
- MYFILE.TXT
- ADA-SW.NOT
-
-
- 3. Full File Reference
- ----------------------
-
- Directory names and file names may be concatenated in order to
- provide a complete reference to a file. When referencing a file in
- the current directory, the file name may be omitted. Examples:
-
- PD2:<ADA>ADA.CRC
- PD2:<ADA.GENERAL>WELCOME.DOC
-
