MSIR.0338 After SIRFIELD (subcmd), alias (alias) of field (field) is no longer produced by PAI because (type) (name) now is

This informational message indicates that a SIRFIELD 'subcmd' command was issued which caused a change in the behaviour of the PAI statement. Prior to this command, the name 'alias' would be output by a PAI statement, but now it will not be. Instead, when occurrences of 'field' are present in a record, PAI will output the 'name', which is either the field name or an alias, as indicated by 'type'.

See the discussion of the PAI statement in the Sir2000 Field Migration Facility Reference Manual.
