The following scheme is suggested since it satisfies all requirements, and would cause the least upheaval to existing users.
Each individual (including certain pseudo individuals such as libraries and administration features) is associated with a unique USER IDENTIFIER, which consists of a sequence of up to 4 letters (commonly initials ) followed by up to 4 digits (the user number, if we like).
All jobs are run under a project number, whose main purpose is to form the basis of the log analysis system. A project number is an integer of up to 4 digits.
With every job running in the machine, the supervisor maintains a job title; if the job is off-line, then this is the job title from the job description; if on-line, it is supplied by CONTROL. The User Identifier and the Project Number will be found in the job title according to the following rules:
job title | project number | user identifier |
---|---|---|
DFH200/... | 200 | DFH200 |
1023DFH200/... | 1023 | DFH200 |
The first component of a file title is a user identifier; if the first component is not quoted, then the user identifier is taken from the job title (see 3 above).
The project number is only quoted at the start of the job title; if it is not quoted explicitly then the integer in the user identifier is taken (see 3 above). If any other (document) title is quoted in a job description, and the first component is missing, then only the user identifier is substituted automatically.
IIT (1033 DFH200/SAMPLE JOB) INPUT P0 FROM FILE (/TEST/1) D1 (/DATA)
The 2 input documents are respectively (DFH200/TEST/1) which is a file, and (DFH200/DATA) which is an input document.
Either | (a) | the project number and user identifier can be quoted after USER as for job description; |
or | (b) | some more convenient notation can be used. |
The only immediate changes for users would be those cases where a file owner does not have the required format; viz:
1001 | CWS | (Whitby-Strevens) | |
291 | SYS | ) | |
) | |||
292 | SYS | ) | pseudo users |
) | |||
etc. | ) |
It is suggested that all users are, as soon as convenient, given definitive user numbers, and urged to adopt the new formats; although this does not have to occur "overnight".
I would further propose:
