is MATCH a volatile function?

[Guest]

I have the following formula: =IF(ISNUMBER(MATCH(B2,'1 31 07 FAS sheet
1'!$AG$2:$AG$65536,0)),"Matched",IF(ISNUMBER(MATCH(B2,'1 31 07 FAS sheet
2'!$AG$4:$AG$58232,0)),"Matched","Unmatched"))

If I manipulate other data outside the ranges in the above formula, the
whole workbook recalculates. I've never seen MATCH referred to as volatile.

Thoughts?

This is helpful thanks. According to the link, the formula below must have
become volatile because it refers to other worksheets and I was inserting
columns.

In 2003 inserting columns will force a calculation (2003 was the first to
allow you to aggregate based on whether the cell was hidden or not). It will
not make the function volatile. However by inserting a row you may have
changed the dependant range which will dirty the cell with the match and
force the recalc.
