This code affects the operation of J justified types in INFLD. If specified, then a null input to a J-type field, as distinct from an explicit input of zero, will return ENTRY padded with spaces to xmax, e.g. ‘ ’. This conforms to the operation of INPUT.SBR as supplied with AlphaACCOUNTING in the UK. If INFLD143 is not specified, then a null input would return ENTRY padded with zeros, e.g. 000000. This conforms to the operation of the assembly language routine as supplied by MicroSabio for AMOS.
