I am having a problem with a FM 6 DB. I have a field for phone and
right now they contain a variety of different formats (with spaces,
with dashes only, with parenthesis ....) Anyway, I need to update
this field (either by script or a calculation field) to contain only
the digits. I know in FM 8 you can use the function filter to only
return the numeric values and not the special characters:

FILTER ( Telephone ; "0123456789" )

Is this possible in FM 6?
