Thank you for the warning!!!!! I use Arc/INFO AML in some cases but as
I am learning more of the REV 9 ArcGis I use AML less and less often.
ALSO- folks be aware of the test and no-test options as they can give
incorrect results if you are not careful.

For those of you who are still using Arc/INFO AML to do things, you
might need to watch out for functionality changes that might have been
implemented inadvertently. For example, a variable quoted by the [QUOTE
] function is not the same as not quoted by the [QUOTE ] function. For
instance, the following statements will produce different results
(ArcInfo 9.0). Among other things, the quote function is often used to
prevent a failure should the variable is a null/empty or an incompatible
type (e.g. a number in this case).
&sv x = 'TEST'
&if [quote %x%] = 'TEST' &then &type (1) X is equal to TEST
&else &type (1) X is not equal to TEST
&if %x% = 'TEST' &then &type (2) X is equal to TEST
&else &type (2) X is not equal to TEST
