Change the file-type to dynamic. It will not give the best performance compared to monitoring file size of a static file type, but over the long-term, avoids sizing issues that are the #1 reason for bad performance. Can you perform an "ANALYZE.FILE {filename}" and post the result? ... david ... David L.

Here is briefly how the attributes are organized, a relatively simple example: Attribute 1 is multivalued with our G/L Period, i.e. 12-01 vm 12-02 vm 12-03 etc. Attributes 2 through 30 are dependent on attribute 1 and contain a variety of dollar amounts that are accumulated for the respective period in attribute 1. At the end of each month, a new G/L Period is inserted into the multivalued position of attribute 1 as well as each of the respective multivalued positions in attributes 2 through 30. Nothing complicated. My question is this and is aimed largely at the technicians at Rocket ... If, at the beginning of the year, I were to insert each of the 12-periods into their respective multivalues in attribute 1 and insert respective <null> multivalues into attributes 2 through 30, thus performing all of the 'inserts' at once, will the processing each month run faster as numbers are simply accumulated into attributes 2 through 30 and no inserting of new multivalues will have to be performed? A couple nuggets of information: This is only an example. In the actual file, these records contain many other attributes and the records overall are relatively large, averaging lengths of about 3,000 according to FILE.STAT These are not my files so reorganizing them is not an option. The heart of this question is, as a (numeric) number is accumulated in an attribute, multivalue or subvalue, what causes the record to 'stretch' in length, thus presumably impacting performance? I would like to think that numeric information is stored in a more 'compact' method than strings, thus using less space within the database ... but what I 'like' and what 'is' are often quite different.
