Hi Alistair, That's because you can't trim a NUMBER field, you can only run mathematical operations on it. But what you can do is cast the number as a string (STR$), then truncate it (RIGHT$), then cast it back to a number (VAL).
Update MYTABLE set MYCOLUMN = val(right$(str$(MYCOLUMN), 4)) Should do the trick.

Once again, having checked the user guide and MI-L archives I am stumped. I have a 9 digit column (integer) which I would like to trim to the last 4 digits... What should be a relatively simple operation is just not working! I'm sure it's a user error! I have MI 7.8 and a table with 6000 records in it. The field I wish to trim has 9 digits for every record, and none exceed the value 390000000. Each time I try (and there's been a few...) to trim the values in this field using Right$(SLA03_Code,4) I get the following error message: Right$: argument 1 has invalid type Has anyone else had this problem or can you see the error (that may well be patently obvious to all you old hands...) that i'm making? Thankyou, Alistair. *************************************************** Alistair Hart GIS Project Officer Health Surveillance Tropical Public Health Unit Network PO Box 1103 Cairns QLD 4870 Ph: 0740 503 628 Fax: 0740 311 440 E: [EMAIL PROTECTED] "Disease ecology is inherently integrative and spatial, and GIS provides the environment in which the biophysical, social, behavioural, and cultural worlds can be combined for a systemic understanding of health and disease" Tim U.
