This is from a OS/ES installation (probably MVT, but could be MVT under control of SVM) where I have one (!) sheet of "endless paper" with lines like those. Text seen indicates it was from the city of Schwerin, not sure if from the VEB Datenverarbeitung (data processing center, a disctrict-wide service provider for using computers, especially mainframes) or some other works or factory. "SVDRUCK" could be Sozialversicherung (social insurance), so maybe they also ran jobs for their own payroll rather than using the services VEB DVFO... And: Yes, of course it looks like /360 console output, because OS/ES is not _that_ different, because of... erm... compatibility and interoperability! Because that's the future! :-) --=20 Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
