Thanks, and thanks to Tony who took the time to scan his hardcopy.

Re: Life of a JOB
I believe the below ACHAP07 member of the MXG Source Library may be the information you requested, as it was presented at SHARE in the 70s and 80s. While it claims to be revised, it's still possibly out of date. Barry /* Copyright (C) 1984,1994 Merrill Consultants Dallas Texas USA */ Status: Has been completely revised. Chapter Seven Events in the Lifetime of an MVS Job/STC/TSO Session. To perform CPE analysis, the analyst must understand the computer system under investigation and know what functions the operating system performs for a task. Although operating systems are different, they all manage the shared resources in response to requests by tasks for those resources. Since the operating system is the manager of the many queues for these requests, a large part of CPE data analysis is to determine who is in what queue, for how long, and why. All operating systems provide some accounting data for each task (job, session, and so forth) that contain time stamps when certain events occur for that task. By comparing these time stamps to the logical structure of the services provided by the operating system, the analyst can understand how an operating system interaction is mapped to the CPE data. By subtracting adjacent time stamps, the duration in certain states (allocation, CPU execution, I/O execution, and so forth) can be determined at the task level. Documentation of CPE data from the vendor often does not tell enough about the meaning of these events. Sometimes you can read the microfiche (when the vendor makes the source available) and perhaps decipher the conditions under which a time stamp is valid, but even then, the experimental confirmation of suspicion is required. By executing tasks that you understand (that is, your own specific job) and by examining the detail data in those detail records written on your tasks, you can gain the necessary knowledge. For SMF data, the MXG program ANALALL will print all variables from all records for any job. The SAS System provides powerful features for manipulating numeric values that contain durations, time stamps, dates, and datetimestamps. All of these variables are stored as numeric values and manipulated as any other numeric value. It is the association of a SAS format (by using the FORMAT statement) that causes the numeric value to be printed as a date, time of day or duration, or datetimestamps: Dates are stored as the number of days (plus or minus) from Jan 1, 1960. MXG always assigns the format DATE7 to date variables, so that the name of the month is printed, and MXG avoids the ambiguity of the MMDDYY and DDMMYY formats (03/05/94 means 05MAR94 in the US but 03MAY94 in Europe!) Eg:DATA; DATE=1; PUT DATE DATE9.; prints as DATE=01JAN1960. Eg:DATA; DATE=1; PUT DATE DATE7.; prints as DATE=01JAN60. Times are stored as seconds (and fractions, if any), and are assigned the TIME12.2 format (for typical SMF time stamps with resolution of tenths and hundredths of a second). Eg: DATA; TIME=43200.99; PUT TIME TIME12.2; prints as 12:00:00.99, (there are 86,400 seconds in a day!). . Datetimestamps are stored as seconds (plus or minus) from midnight on January 1, 1960, and are assigned the DATETIME21.2 format (if they are standard SMF datetimestamp values). Eg.: DATA; DATETIME=1262217600.99; PUT DATETIME DATETIME21.2; prints as 31DEC1999:00:00:00.99. A note on the length of datetime variables. SAS numeric variables are floating point numbers, and are normally stored in 8 bytes (one for the exponent, seven for the mantissa). Prior to Change 19.272 in January, 2002 this was true: MXG overrides the stored length default and specifies LENGTH as DEFAULT=MXGLEN; only a few variables need the full 8 byte length, and using 4 bytes per variable saves significant DASD space in your MXG datasets. There is one class of variables, however, that do require 8 bytes of storage: datetimestamp values, because four bytes is not large enough to fully resolve the 10-digit value of current datetimestamps. In fact, if you should store a datetimestamp in only four bytes, the time values will be as much as 255 seconds less than reality. Thus MXG assigns a length of 8 bytes for all datetimestamp values. To further save storage, MXG may keep only the start datetime value and the duration, requiring only 12 bytes, instead of both timestamps which would require 16 bytes, since the end datetime can always be reconstructed by addition. Change 19.272 changed the default stored length from 4 to 5 on EBCDIC and from 4 to 6 on ASCII SAS systems. See that change text. Originally, all MXG datetimestamp variables ended with TIME (for example, READTIME), and all MXG duration/time variables ended with ...TM (for example, CPUTCBTM), but that was back when I created all of names of all of the variables. Now, I
