The INFLDPS code affects the operation of P and S types in INFLD.SBR. The default is for a P type field to be a U.S.-format phone number, and an S type field to be a secure (non-echoed) input. This conforms to the operation of the standard AMOS version of INFLD. If INFLDPS is specified, then the meanings of the two types are reversed. This corresponds to the operation of INPUT.SBR with AlphaACCOUNTING in the UK, which uses type P for non-echoed passwords.
