Holding Data Using Across Command

The HOLD command lets you retrieve and process data, then hold the results for further processing.  The resulting data file contains the original fieldnames and values requested per verb (PRINT, SUM, COUNT, LIST) and sort (BY) commands, or generated using the ACROSS command.


For example, compare the report requests below.  Both reports are summing gross pay for individual employees by pay period, but one is using the sort BY and the other is using the sort ACROSS.  


Note:  The tables below are best viewed with the navigation pane hidden.

As you can see, the Master File Descriptions (MFD) generated for the hold files are very different.  In the second request, the resulting values for the field PH:PAYPERIOD have become individual data columns.  This technique is especially useful when you need to condense multiple rows of data for an individual into a single row of data.  


When generating reports from the hold file data, either the fieldname or the alias can be used in the request.  For example:to identify employee's who received pay for both the September and December pay periods:


table file permrpt

print ph:ssa

Where (ph:200409 gt 0) and (ph:200412 gt 0)



Refer to your FOCUS documentation or the CIRS User Manual for more information on creating and using hold files.
