7.63.1 KEEP_COUNT Parameters
Specifies from 1 to 50 fields that are to be counted by the KEEP_COUNT command.
Fields specified in this parameter must be defined in the LANSA data dictionary or defined within this function by a DEFINE command. Expandable group expressions are valid in this parameter.
The fields specified may be numeric or non-numeric. It is possible to count the changes of a non-numeric field.
Specifies the field that is to hold the result of the count of the field(s) specified in the OF_FIELD parameter.
The field specified in this parameter must be numeric and must be defined in the LANSA data dictionary or defined in this function with a DEFINE command.
This field is reset at the beginning of each SELECT/SELECTLIST loop.
Specifies the condition under which the fields are to be counted.
*SELECTED, which is the default value indicates, that the count should continue until the SELECT/SELECTLIST loop terminates (ie: all selected information).
Otherwise, specify a list of 1 to 20 field names (alternatively, enter an expandable group expression). The count continues until one or more of the fields in the list changes value. When one or more of the fields changes value the "accumulator" is reset to its null value and a new count cycle is started.
The "accumulator" is the work field keeping the count of the changes.
See the examples section for more details of how this parameter is used.
