RE: UDF limitation

Rob,

Unfortunately that is consistent with IBM functions.

Select fld1, fld2 as xxx, substr(fld2, 3, 1) from file

Works fine, but

Select fld1, fld2 as xxx, substr(xxx, 3, 1) from file

Complains the xxx isn't in the file. To make it more annoying you can sort
on the renamed fields however. It would appear that the syntax checker is
single pass and doesn't account for renames.
