Have done some data transformation from Siemens BS2000 mainframes to GNU/Linux pc with GnuCOBOL 2.0. Most simple method is: - convert your ISAM files on the original platform (mainframe) to flat files with all binary and packed decimal data fields converted to zoned decimal fields, - transfer those files with ftp to the pc environment, - convert those transferred files to the ISAM files needed. For conversion is of cource needed an utility program. Having the original file description in cobol source format will help. Regards, Fred Mobach
