Optional parameter available in standalone SUDAAN versions only.
On the PROC statement use this parameter to specify the name of a file containing records associating long variable names and labels with their shortened versions on an input file in SASXPORT format. If this parameter is not supplied, SUDAAN will look for a file named NAMEFILE.STX. If SUDAAN cannot find a name file, whether the name is supplied explicitly or by default, or if the (long) variable names used within the SUDAAN program are not on the given name file, then SUDAAN will not recognize them when reading the main data file in SASXPORT format.
On the OUTPUT statement use this parameter to specify the name of a file in SASXPORT format to contain any records associating long variable names and labels with their shortened versions on the main output file. If this parameter is not supplied, and there are one or more variable names or labels which have to be truncated, SUDAAN will use the name NAMEFILE.STX. Note, however, that in no case will SUDAAN overwrite a file already using the specified filename unless the REPLACE option is present on the OUTPUT statement.
