# Change xxLAST.TXT File

You no longer need to have an xxLAST.TXT task to merge application-specific information into these standard OSAS files: OSCNVT, OSCNVT.HDR, OSFRM, OSTPL, OSORDER, GENERAL Report Writer Data Dictionaries, and BASIS Data Dictionaries. You also do not need to use the xxLAST.TXT file to merge the new Change Field information into OSFD and OSFH. The installation process will automatically look for these application-specific files and, if they exist, merge them into the necessary OSAS files.
