MONTHLY
MONTHLY [yymm]
[mm ]
The MONTHLY command performs data extraction based on a calendar month.
When you execute this command, the start and stop dates are set to the
proper dates based on the month and year of the data extracted.
The name of the output file consists of the letters RXMO followed by the
last two digits of the year and the two-digit number of the month being
extracted. For example, March 1990 would be output to a file named
RXMO9003.
Enter one of the following:
MONTHLY To extract data from the current (default)
month.
MONTHLYmm To extract data for a specific month from this
year's data (where mm is a number from 01 to
12).
MONTHLYyymm To extract data for a specific month and year
(where yymm is a single number composed of the
last two digits of the year and the two-digit
month number).
For example, February 1991 would be MONTHLY
9102.
If you do not specify the log file before executing the MONTHLY command,
it defaults to the file LOGGLOB.SCOPE.SYS.
The type of data extracted and the level of summarization of that data
follow the normal rules for EXTRACT and can be set before executing the
MONTHLY command. These settings are honored unless the monthly output
file already exists. If it does, data is appended to it based on the
original type of data selected.
The MONTHLY command has a special feature. It opens the previous month's
extracted file and checks to see if it is filled--whether it contains
data extracted up to the last day of the month. If not, the MONTHLY
command appends data to this file to complete the previous month's
extraction.
For example, a MONTHLY command is executed on May 7, 1991. This creates
a log file named RXMO9105 containing data from May 1 through the current
date (May 7).
On June 4, 1991, another MONTHLY command is executed. Before the
RXMO9106 file is created for the current month, the RXMO9105 file from
the previous month is opened. When it is found to be incomplete, data is
appended to it to complete the extraction through May 31, 1991. Then,
the RXMO9106 file is created to hold data from June 1, 1991 to the
current date (June 4).
As long as you execute the MONTHLY command at least once a month, this
feature completes each month's files before the next month's file is
created. Whenever you see two monthly files adjacent to each other--for
example, RXMO9005 and RXMO9006--you can assume safely that the first file
is complete for that month, and it can be archived and purged.
